GPD7 – Dataradio G3 Engineering Report – Annex A – Part A2 Modulation Source A8 Page 1 of 1 156-90000-501 Dataradio© FCC submission MODULATION SOURCE DESCRIPTION: RULE PART NUMBER: 2.1047, 90.535 The G3+ modem generates digitized multi-level frequency shift keying modulating signal. This digital modulation scheme is produced by the main CPU in conjunction with the DSP processor as follows: The main CPU processes incoming binary data to comply with data layer requirements, and then this binary stream is fed to the DSP processor which runs the functions of applying Forward Error Correction (FEC), interleaving and scrambling in binary and, from it, generates an NRZ for encoding and pulse shaping. The digital processing computes the binary differential and maps the binary stream into a symbol stream. The binary stream is processed as stream of clusters of multiple-bits as required by multiple level FSK modulation type. The number of levels of the digital symbol stream corresponds to the numbers of levels of NFSK modulation. The digital symbol signal has further applied a pulse shaping filter through the DSP. The pulse-shaping filter is in Raised Cosine family and the appropriate equation designs the filter characteristic together with the 3dB cutoff frequency. The equation trim factor, which for RC family is the cosine weight “α”, is set according to the bit rate selected and channel bandwidth as follows: Bit rate levels FSK Symbol rate Pulse shape and modulation type Acronyms/ factor / 3dB cutoff frequency Deviation Occupied Bandwidth 128000 bps 16 32000 bauds Raised Cosine 16 Levels Frequency Shift Keying RC16FSK α=0.4 16000Hz ± 8.3 KHz 27666Hz The pulse-shaped signal has further applied a amplification constant which adjusts the transmitter deviation level and then is fed to the CODEC for digital to analog conversion. The resulting waveshape applied to the FM modulator will then produce a compact RF spectrum such that, when using proper frequency deviation, to fit inside the restrictive limits inherent to the intended channel bandwidth. The same processes but backwards happen to demodulate the modulated symbols into data stream TX Data Test Pattern: The transmit “test data pattern” command produces a 2047 bit pseudo-random pattern. This pattern is generated by the internal software using the polynomial X 11 +X 9 +1 form and a 12-bit shift register. Initial value of the register is 111111111110 (FFE hex). The 2047 bit sequence is repeated thereafter as long is necessary to complete the test duration (55 sec). This pattern is applied to the DSP processor data input for encoding and pulse shaping as described above.

GPD7 – Dataradio G3 Engineering Report – Annex A – Part A3 Occupied Bandwidth A3 Page 1 of 2 156-90000-501 Dataradio© FCC submission Transmitter Occupied Bandwidth and Emission Designator Determination RULE PART NUMBER: 2.201, 2.202,2.1049 (h), 90.543(d), 90.27.53(d)(4) Necessary Bandwidth Measurement (90.202.(c)(4)) and Emission Designator This radiomodem uses digital modulation signals, passing through a pulse shaping DSP implemented low-pass filter to an FM transceiver. The equations for the filter are Nyquist-based being driven by the data symbol rates, they are detailed in modulation source description paragraph, in next page. The necessary bandwidth calculation for this type of modulation is not covered by paragraphs (1), (2) or (3) from 2.202(c), the result exceeding by far the real necessary bandwidth obtained through simulations or measurement. Therefore, the approach outlined in (2.202(c)(4)) is applicable in this case. The results of 99% Occupied Bandwidth measurement are: Bit rate Symbol rate Filter equation Deviation (1kHz tone) Occupied Bandwidth Emission designator 128000 bps 32000 bauds Raised Cosine ± 8.3 KHz 27.67kHz 28K0F1D The value of the necessary bandwidth (and implicitly of the emission designator) doesn’t exceed the authorized bandwidth of 50kHz (90.543(d)). Occupied Bandwidth Measurement (90.202(c)(4) The Occupied Bandwidth measurement option of the instrument (8563EC spectrum analyzer from Agilent) calculates and provides the values used above for the emission designator. The percentage setting of the measurement has been set to 99% following the definition of the Occupied Bandwidth “the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5 percent of the total mean power radiated by a given emission” (FCC 2.202) The measurement has been performed using the Occupied Bandwidth Measurement Function of 8563EC the resulting value was recorded as Occupied Bandwidth.
