[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
