Receiver with parallel correlator for spread spectrum digital transmission |
摘要 |
A receiver of a handset transceiver, in a wireless telephone system having a plurality of wireless handset and a base unit having a base transceiver. Each handset has 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 for receiving a spread spectrum signal comprising successive chips representing successive symbols. Each receiver has 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. A parallel correlator of the receiver detects a peak bin and provides the peak bin and two adjacent bins. An error estimator of the receiver adjusts the demodulation parameters in accordance with the peak bin and the two adjacent bins to optimize demodulation of the spread spectrum signal. |
