1 TM AN9633 Processing Gain for Direct Sequence Spread Spectrum Communication Systems and PRISM® Introduction This application note addresses the concept of processing gain (PG) of Direct Sequence Spread Spectrum (DSSS) systems. The PRISM chipset is used to implement DSSS radio designs. The processing gain provides the unique properties to the DSSS waveform primarily in terms of interference tolerance. The PG of a DSSS system is centered around the utilization of random codes which are used in conjunction with the data. These random codes are referred as Pseudo Noise (PN) codes. The HSP3824 provides this coding capability for the PRISM. Description In a DSSS system random binary data with a bit rate of r b bits per sec (bps) is multiplied (Exclusive Ored) by a pseudorandom binary waveform, which is at much higher rate and it provides the frequency spreading operation. This pseudorandom (PN) binary source outputs symbols called chips at a constant chip rate r C chips per sec (cps). This is a random, noise like signal and hence the name PN signal. The chip rate is always higher than the bit rate, and the ratio of the chip rate to the bit rate is defined as the processing gain (PG) [3]. The PG is a true signal to jammer (interference) ratio at the receiver after the despreading operation (removal of PN). The rate of the PN code is the one that defines the bandwidth of the transmitted spread waveform. The receiver of a DSSS system must remove the spreading as the first step in the demodulation process. During the despreading operation the receiver must generate a phase locked exact replica of the pseudorandom spreading waveform to match the transmitted signal. This is achieved by the code acquisition, and code tracking loops embedded in the HSP3824. The receiver PN sequence must be exactly in phase with the transmitted PN sequence, and this is achieved by correlation techniques. DSSS Transceiver A DSSS transmitter is shown in Figure 1. The data is denoted by d(t), the spreading signal is denoted by c(t), and the spread waveform q(t) is fed to the BPSK modulator operating at a carrier frequency f C , and the transmitted signal is denoted by x(t). A text book conceptual block diagram of a DSSS receiver is depicted in Figure 2. Note that PRISM is architected to perform the despreading function at baseband (HSP3824) rather than at RF as shown on Figure 2. This example is used for illustration of the concept and not to reflect the actual PRISM implementation. The received signal for this text book example is the combination of the transmitted spread spectrum signal and a narrow band jammer x J (t). The locally generated despreading sequence is denoted by c’(t), and should be equal to c(t). The despread signal is then band pass filtered before data demodulation and d’(t) should be equal to d(t). PG Benefits The primary benefit of processing gain is its contribution towards jamming resistance to the DSSS signal. The PN code spreads the transmitted signal in bandwidth and it makes it less susceptible to narrowband interference within the spread BW. The receiver of a DSSS system can be viewed as unspreading the intended signal and at the same time spreading the interfering waveform. This operation is best illustrated on Figure 3. Figure 3 depicts the power spectral density (psd) functions of the signals at the receiver input, the despread signal, the bandpass filter power transfer function, and the band pass filter output. Figure 3 graphically describes the effect of the processing gain on a jammer. The jammer is narrow, and has a highly peaked psd, while the psd of the DSSS is wide and low. The despreading operation spreads the jammer power psd and lowers its peak, and the BPF output shows the effect on the signal to jammer ratio. FIGURE 16.

PRISM and design is a trademark of Intersil Americas Inc. 2 If for example, BPSK modulation is used and an Eb/No of lets say 14dB is required to achieve a certain BER performance, when this waveform is spread with a processing gain of 10dB then the receiver can still achieve its required performance with the signal having a 4dB power advantage over the interference. This is derived from the 14dB required minus the 10dB of PG. The higher the processing gain of the DSSS waveform the more the resistance to interference of the DSSS signal. The classical definition of processing gain is the 10 Log number [r C /r B ] 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. To this end these PN signals must posses certain mathematical properties to be useful as part of a DSSS system. Primarily the PN codes that are useful must have very good autocorrelation and crosscorrelation properties as well as maintaining some randomness properties. The DSSS receiver is utilizing a reference PN sequence which is a replica to the transmitted sequence and when it detects correlation between the reference and the incoming sequences it declares initial a…
