[Detection of an LPI Signal] An LPI signal is generated by binary modulation of an m-sequence from a 10-stage shift register, (L = 1023) and, hence, the number of chips per information bit is 1023. The output of the shift register is mapped into the bipolar sequence
The transmitted sequence of chips is corrupted by AWGN, so the received signal sequence at the output of the chip matched filter is
where the binary data bit s is either + 1 or -1, for the entire sequence 0 ≤ k ≤ 102 3.
1. Generate them-sequence {ck} and verify Equation (12.3.2) is satisfied.
2. Use them-sequence generated in part 1 to construct the received signal sequence {rk} and plot it fork= 1, 2, … , 1023, when the variance of the Gaussian noise
