Equalizer Sharing in Wireless Communications: Simulation Study

摘要

This paper presents a simulation study for code-division multiplex system, over time varying channels. The scheme investigated here uses a sharing technique for the signal processing unit between the transmitter and the receiver to improve the performance of the system. This technique minimizes the effect of inter-symbol interference (ISI). The data itself is transmitted in the form of blocks of data symbols separated by blocks of no signal. The appropriate length of each data block depends on the channel parameters expected and the allowed complexity. The impulse response is required to be known at the transmitter which is the requirement for all systems that employ coding at the transmitter.
