The Wigner-Ville distribution (WVD) is a valuable tool for time-frequency signal analysis. In order to implement the WVD in real time, an efficient algorithm and architecture have been developed which may be implemented with-commercial components. This algorithm successively computes the analytic signal corresponding to the input signal, forms a weighted(More)
— To achieve unlimited concurrency and hence throughput in an area-efficient manner, a sliding block Viterbi decoder (SBVD) is implemented that combines the filtering characteristics of a sliding block decoder with the computational efficiency of the Viterbi algorithm. The SBVD approach reduces decode of a continuous input stream to decode of independent(More)
The IS-856 system delivers high spectral efficiency on the forward link by using dynamic link adaptation, hybrid ARQ and multiuser diversity scheduling. The channel coding/modulation scheme used on the forward link is designed to support incremental redundancy for hybrid ARQ, while maximizing the coding gain over static channels. This paper presents the(More)
Two patients with presumed impending cortical necrosis, after haemolytic uraemic syndrome in one and after concealed accidental haemorrhage in the other, were treated by local infusion of urokinase and heparin into the renal artery. Both recovered and one regained normal renal function. Local infusion of anticoagulants or thrombolytic drugs into one renal(More)
Interference cancellation (IC) techniques significant capacity gains are presented in this paper for CDMA2000 1x base station receiver. In addition to performance gain from conventional IC, hybrid ARQ gain is achieved effectively without interlaced transmission or feedback on the forward link (FL). A new definition of CDMA capacity, based on equivalent(More)
