Abstract:
A receiver for receiving a spread spectrum signal comprising successive chips representing successive symbols, the receiver comprising:(a) one or more demodulation loops for demodulating the received spread spectrum signal, wherein each demodulation loop is characterized by one or more demodulation loop parameters; (b) a parallel correlator for detecting a peak bin and for providing the peak bin and two adjacent bins; and (c) an error estimator for adjusting the demodulation parameters in accordance with at least one of the peak bin and the two adjacent bins to optimize demodulation of the spread spectrum signal, wherein each handset comprising a handset transceiver for establishing a time-division multiple access (TDMA) link over a shared channel with the base unit via the base transceiver, in which each handset communicates during an exclusive time slot of a TDMA scheme that allocates time slots to handsets during an exclusive time slot of a TDMA scheme that allocates time slots to active handsets.
