Power limitation is carried out by supplying power independently to each circuit and keeping power supply voltage constant. Modulation circuit PLL circuit RF mixture, amplifier circuit Also the APC function is employed to keep the output voltage constant by comparing pre-set power value to detected power value. RF circuit 1) Modulation block The equipment performs PSK or CCK modulation/demodulation and spread/back spread spectrum by base band processor HFA3861A. The spread code used is 11 bit (transmission rate is 1, 2 Mbps) or 8 bittransmission rate is 5.5, 11 Mbps Code rate is 11 MChips/s. 2) Oscillation block The equipment has two VCO's which are controlled by the frequency synthesizer referencing to 44.0 MHz. Oscillation frequencies are 748 MHz and 2038 to 2088 MHz. 3) IF block The 748MHz oscillation signal is divided into two frequencies in the mixer HFA3783. Then it is mixed with modulation signal and be a 374MHz IF signal. The IF signal is amplified by the HFA3783 and then brought to the SAW filter (made by SAWTEK, model 855653, center frequency is 374MHz, and bandwidth is ± 8.5). HFA3783 also incorporates a receiving circuit. For receiving, modulation signal is selected from IF signals. During receiving, AGC circuit works to control gains according to the receiving power. 4) RF block The oscillation signal of 2038 to 2088 MHz is input to the mixer HFA3683 and mixed with IF signal to be RF signal. Then the RF signal passes band-pass filter to remove spurious emission and is amplified for about 27dB by power amplifier HFA3983. The amplified RF signal passes the transmitting/receiving switch, band-pass filter and antenna switching switch, and then is radiated to the air. The received RF signal passes antenna switching switch, band-pass filter and transmitting/receiving switch, and then is amplified by a low noise amplifier incorporated in HFA3683. The amplified signal is then mixed with 2038 to 2088 MHz signal to be IF signal.

HFA3861A Data Rate Symbol Rate Chip Rate 1 Mbps 1 Msps 11 Mcps 2 Mbps 1 Msps 11 Mcps 5.5 Mbps 1.375 Msps 11 Mcps 11 Mbps 1.375 Msps 11 Mcps The HFA3861 transmitter is a Direct Sequence Spread Spectrum Phase Shift Keying (DSSS PSK) modulator. It can handle data rates of up to 11Mbps. The various modes of the modulator are: Modulation Data Rate DBPSK 1 Mbps DQPSK 2 Mbps CCK 5.5 Mbps CCK 11 Mbps These implement data rates as shown in Table 3. The major functional blocks of the transmitter include a network processor interface, DPSK modulator, high rate modulator, a data scrambler and a spreader, as shown in Figure 7. CCK is essentially a quadra- phase form of M-ARY Orthogonal Keying. A description of that modulation can be found in Chapter 5 of: “Telecommunications System Engineering”, by Lindsey and Simon, Prentis Hall publishing. The preamble is always transmitted as the DBPSK waveform while the header can be configured to be either DBPSK, or DQPSK, and data packets can be configured for DBPSK, DQPSK, or CCK. The preamble is used by the receiver to achieve initial PN synchronization while the header includes the necessary data fields of the communications protocol to establish the physical layer link. The transmitter generates the synchronization preamble and header and knows when to make the DBPSK to DQPSK or CCK switchover, as required. The classical definition of processing gain is the 10 Log number [rC/rB] in dB. By this definition a system that has a data rate of 1MBPS and a chip rate (rate of PN code) of 1MCPS will have a PG of 10.41dB. Using the PRISM chip set each data bit is x-ored with an 11 bit sequence for this particular example. The processing gain can be then viewed as the 10Log[11]dB where 11 is the length of the PN code. If a code with a length of 16 bits is to be used then the processing gain is equivalent to 10 Log[16] dB or 12.04dB. Data Demodulation in the CCK Modes In this mode, the demodulator uses Complementary Code Keying (CCK) modulation for the two highest data rates. It is slaved to the low rate processor which it depends on for acquisition of initial timing and phase tracking information. The low rate section acquires the signal, locks up symbol and carrier tracking loops, and determines the data rate to be used for the MPDU data. The demodulator for the CCK modes takes over when the preamble and header have been acquired and processed. On the last bit of the header, the phase of the signal is captured and used as a phase reference for the high rate differential demodulator. Control of the demodulator is then passed to the high rate section. The signal from the A/D converters is carrier frequency and phase corrected by a complex multiplier (mixer) that multiplies the received signal with the output of the Numerically Controlled Oscillator (NCO) and SIN/COS look up table. This removes the frequency offset and aligns the I and Q Channels properly for the correlators. The sample rate is decimated to 11MSPS for the correlators after the complex multiplier since the data is now synchronous in time. The Fast Walsh transform correlation section processes the I and Q channel information. The demodulator knows the symbol timing, so the correlation is batch processed over each symbol. The correlation outputs from the correlator are compared to each other in a biggest picker and the chosen one determines 6 bits of the symbol. The QPSK phase of the chosen one determines two more bits for a total of 8 bits per symbol. Six bits come from which of the 64 correlators had the largest output and the last two are determined from the QPSK differential demod of that output. In the 5.5Mbps mode, only 4 of the correlator outputs are monitored. This demodulates 2 bits for which of 4 correlators had the largest output and 2 more for the QPSK demodulation of that output for a total of 4 bits per symbol.

A CW signal generator is stepped across the passband of the receiver in 50 kHz increments. At each point the signal generator level required to obtain the recommended bit error rate is recorded. The jammer to signal ratio (J/S) is then calculated. The worst 20% of the J/S points is discarded. The lowest remaining J/S ratio is used to calculate the processing gain. Calculation Of Processing Gain: The processing gain was determined by measuring the jamming margin of the E.U.T. and using the following formula: Jamming Margin = G p - (S/N) out - L sys For a receiver using non-coherent detection the value (S/N) out is calculated using the formula: P e = (1/2)EXP{-E/2N o } where P e is the probability of error (minimum Bit Error Rate required for proper operation). E/N o is (S/N) out for example, for a bit error rate of 10 -4 a S/N ratio of 12.3 dB is required. L sys (system losses) is assumed to be 2 dB.
