WIRELESS COMMUNICATION SYSTEM USING BLOCK FILTERING AND FAST EQUALIZATION-DEMODULATION AND METHOD OF OPERATION

摘要

There is disclosed a transceiver (400) for use in a base station (110) of a fixed wireless network (100) that communicates with a plurality of subscriber transceivers via time division duplex (TDD) channels. The transceiver (400) comprises: 1) a receiver front-end for receiving data burst transmissions from the plurality of subscriber transceivers in an uplink portion of a TDD channel, wherein the receiver front-end demodulates the received data burst transmissions into a digital baseband signal in-phase (I) signal and a digital baseband quadrature (Q) signal; 2) a first frequency domain feedforward equalization filter (440) for receiving the I signal; 3) a second frequency domain feedforward equalization filter (440) for receiving the Q signal; 4) an adder (450) for producing a combined symbol estimate sequence; 5) a slicer (452) for receiving and quantizing the combined symbol estimate sequence; and 6) a time domain feedback filter (458) for generating a symbol correction sequence.
