Patent ID: 6963546

Claim:
A receiver for use in a time division duplex communication system using code division multiple access, the system communicating using multiple communication bursts in a time slot, the receiver comprising: an antenna for receiving radio frequency signals including the multiple communication bursts; a demodulator for demodulating radio frequency signals to produce a baseband signal; a channel estimation device for estimating a channel response for the bursts; a successive interference cancellation joint detection (SIC-JD) device comprising: a first joint detection block for detecting data within the baseband signal for a first group of bursts of the multiple bursts; a first interference construction block for constructing an estimate of interference of the first group bursts; a subtractor for subtracting the first group interference from the baseband signal; a second joint detection block for detecting data within the subtracted signal for a second group of bursts of the multiple bursts; a first matched filter for processing the baseband signal to match symbol responses of the data signals in the first group; and a second matched filter for processing the subtracted signal to match symbol responses of the data signals in the second group; and wherein an output of the first and second joint detection blocks are soft symbols, the SIC-JD device further comprising a first and second soft to hard decision block for converting the first and second joint detection block outputs into hard symbols.
