    • Arithmetic Acceleration Techniques for Wireless Communication Receivers 

      Das, Suman; Rajagopal, Sridhar; Sengupta, Chaitali; Cavallaro, Joseph R. (1999-10-20)
      We develop techniques to accelerate the implementation of the next generation wireless communication algorithms in hardware. We discuss an implementation of a key computationally intensive baseband algorithm for joint ...
    • Fast Multi-user Detector for a Time-varying CDMA System 

      Das, Suman; Cavallaro, Joseph R.; Aazhang, Behnaam (1997-07-01)
      This paper investigates methods to reduce the amount of computation needed to detect information bits using a linear detector for a CDMA system. We show windowing technique coupled with pipelining can reduce the amount of ...
    • Low Complexity Iterative Multiuser Detection and Decoding for Real-Time Applications 

      Das, Suman; Erkip, Elza; Cavallaro, Joseph R.; Aazhang, Behnaam (2005-07-01)
      This paper presents a low-complexity multiuser decoding technique that can be implemented in real time for a convolutionally coded direct sequence code division multiple access (DS-CDMA) system. The main contribution, ...
    • Maximum Weight Basis Decoding of Convolutional Codes 

      Das, Suman; Erkip, Elza; Cavallaro, Joseph R.; Aazhang, Behnaam (2002-11-01)
      In this paper we describe a new suboptimal decoding technique for linear codes based on the calculation of maximum weight basis of the code. The idea is based on estimating the maximum number locations in a codeword which ...
    • Multiuser Information Processing in Wireless Communication 

      Das, Suman (2000-09-20)
      Wireless channel is not very conducive towards error-free raw data transmission. On the other hand the tremendous growth in wireless services has made the channel bandwidth a scarce resource and effective utilization of ...
