Acquisition schemes for acquiring pseudonoise (PN) signals in a frequency hopping (FH), spread spectrum (SS) system are presented. For the purpose of acquiring the PN code the received signal is modeled by an autoregressive (AR) process. The parameters of the AR process are determined by identifying a related set of parameters called the partial correlation coefficients. The power spectrum of the received signal and hence the PN code is estimated from the identified AR parameters. The high accuracy of the estimated PN codes permits the use of a simple error correcting logic to accelerate the acquisition process.
