Performance of a Parallel Acquisition Scheme for a Spread-Spectrum Packet Radio Communication

A matched-jlter (MF) parallel acquisition scheme is proposed f ir a direct-sequence (DSI spread-spectrum (SS) &et radio communimtion The pamllel acquisition scheme consists of a bank of N parallel.I- Q noncoherent MF's Autocorrelation sidelobes are considered fir preamble detection Packet loss probabilities f ir the acquisition scheme are derived f ir an AWGN and a &t Rayleigh w i n g channels. I t is shown that autocorrelation sidelobes of PN codes degrade the perfirmance of the acquisition scheme. Also it is shown that the plrallel acquisition scheme achieves smaller packet loss probability than the serial acquisition scheme f ir both an AWGN and a &
