Performance of combined SAW convolver/serial-search acquisition for DSSS system with single-tone jamming
A new combined matched-filter serial search PS code acquisition scheme based on surface acoustic wave (SAW) convolver preamble processing is presented in which the correct detection of preambles results in a residual uncertainty of just a few code chips, to be searched sequentially and tracked. The performance for this scheme in AWGN and single-tone interference channel is studied, considering the noise in the local reference generator. The conclusion shows that the presence of noise in the reference signal has a stronger influence on preamble processing and mean acquisition time of a system than merely reinforcing the channel noise power.
