Transmitter-Based Minimization of Error Rates in the Downlink of Wireless Systems

Abstract

Using CDMA technology, one has to contend with interference in frequency-selective channels caused by multipath propagation and fading. Transmitter-based methods such as zero forcing joint transmission and transmit Wiener filter only reduce the bit error rate indirectly and do not exploit the knowledge of the transmit data symbols. Nonlinear optimization… (More)
