    • Modeling of Welkin RF in a DSSS System 

      Guo, Yuanbin (2000-09-20)
      In this report, the author studied the methodology of distortion-true software modeling for RF (radio frequency) in a DSSS W-CDMA system. A complete end-to-end testbed based on the Welkin RF system is built by SystemView ...
    • Optimal Signaling Strategies for Symmetric and Asymmetric Bit-Rate Communication Services in the Presence of Crosstalk 

      Gaikwad, Rohit; Baraniuk, Richard G. (1999-01-15)
      We have invented a new modem technology for transmitting data on conventional telephone lines (twisted pairs) at high speeds. This discovery is timely, as new standards are being developed for this Digital Subscriber Line ...
    • Quantization of Sparse Representations 

      Boufounos, Petros T.; Baraniuk, Richard G. (2007-01-16)
      Compressive sensing (CS) is a new signal acquisition technique for sparse and compressible signals. Rather than uniformly sampling the signal, CS computes inner products with randomized basis functions; the signal is then ...
    • Reconfigurable stream processors for wireless base-stations 

      Rajagopal, Sridhar; Rixner, Scott; Cavallaro, Joseph R. (2003-10-20)
      This paper presents the design and use of reconfigurable stream processors for the physical layer processing in wireless base-stations. Stream processors, traditionally used for high performance media processing, use ...
    • Reduced Rank Algorithms for Wireless Space-Time Channels 

      Ndili, Obianuju (2000-05-20)
      The estimation of channel coefficients constitutes a major function of the receiver. It is also an important step in the signal detection process at the receiver, in a wireless communication system. To describe the space-time ...
    • W-CDMA real-time algorithm implementation and evaluation 

      Jones, Bryan Allen (2000-05-20)
      This paper describes a platform to enable and explore the design and implementation of next-generation CDMA wireless base stations. A DSP and FPGA-based multiprocessor board is integrated into a Simulink-based wireless ...
