Throughput and PN codephase acquisition for packet CDMA without preamble

  title={Throughput and PN codephase acquisition for packet CDMA without preamble},

  journal={2008 Canadian Conference on Electrical and Computer Engineering},
In CDMA packet transmission, it is customary to start each packet with a preamble consisting of pseudo-random (PN) code with no data modulation. The preamble facilitates receiver acquisition of the spreading code alignment and this is essential for decoding the spread spectrum signal. Since packets are short, matched filters are employed to provide rapid acquisition and, in this case, we use a segmented matched filter that can provide codephase alignment even when there is data modulation. We… CONTINUE READING
