    摘要: The present invention is a receiver which includes a blind code detection device for determining the identity of a plurality of channels over which information is to be transmitted when the identity of all channels is not known by the receiver. The blind code detection device generates a candidate channel list filled with the identify of selected channels out of the plurality of channels. A multi-user detection device, responsive to the blind code detection device, processes those channels in the candidate code list.

    摘要: A method for differential phase evaluation of M-ary communication data is employed in which the data consists of N sequential symbols r1 . . . rN, each having one of M transmitted phases. Selected sequences of N−1 elements that represent possible sequences of phase differentials are evaluated using multiple-symbol differential detection. Using r1 as the reference for each phase differential estimate, sN−1 phase differential sequences are selected in the form (P2i, P3i, . . . , PNi) for i=1 to s for evaluating said symbol set, where s is predetermined and 1

    摘要: In a method for full discontinuous (DTX) control in a receiver in a wireless communication system it is determined if full DTX is allowed in a current timeslot. If not, then a full DTX indicator is set for the previous frame to false and the method ends. If full DTX is allowed, then it is determined if a special burst has been detected. If so, then the full DTX indicator is set for the previous frame to true and the method ends. If a special burst has not been detected, then it is determined if a transport format combination indicator (TFCI) has been accepted. If the TFCI has been accepted, then the full DTX indicator is set for the previous frame to false and the method ends. If the TFCI has not been accepted, then the method ends without setting the full DTX indicator for the previous frame.

    摘要: Enhanced methods for channel quality estimation utilize soft symbol output data to generate a statistic or set of statistics that are representative of BER for each of a plurality of bursts corresponding to a composite channel. The statistics are mapped into a BER estimate to generate individual BER estimates for each of the plurality of bursts. The individual BER estimates are combined to obtain an estimate of the BER for the entire composite channel. Alternatively, the BER estimate for the composite channel may then be mapped into a quality estimate for the composite channel using a monotonic function.
