Abstract:
A method for acquiring a pilot signal in a code division multiple access (CDMA) receiver, the CDMA receiver including at least one receiver finger, the method comprising the steps of:storing a predetermined number of samples of a received signal;incrementing a real time linear sequence generator (RT LSG);loading a state of the RT LSG into a non-real time LSG (NRT LSG) at a particular point in time relative to storing the predetermined number of samples;repetitively correlating stored samples and contents of the NRT LSG, producing correlations;incrementing the NRT LSG after correlating to establish an NRT LSG alignment value;selecting a set of best correlations;providing an NRT LSG alignment value which corresponds to one of the set of best correlations to a finger linear sequence generator associated with the at least one receiver finger; anddetecting the received signal at the at least one receiver finger using the finger linear sequence generator.
