Reduction of Bit Error Probability during Parallel Transmission of Information in a MIMO System

Radiophysics and Quantum Electronics Aims and scope

Abstract

We consider cellular communication systems with antenna arrays at both link ends, in which the data transmission is performed via parallel eigenchannels under conditions of a scattering medium. To reduce the bit error probability, we propose a method of information transmission based on the use of only part of the eigenchannels with maximum signal-to-noise ratios and ensuring a tradeoff of the data-transmission rate against the bit-error probability. Eigenchannels are separated into energy-strong and energy-weak channels with the help of the threshold technique. Two possible versions of using the proposed method under conditions of a random multipath spatial channel are studied. The results of numerical simulation in the case of Rayleigh fading of signals confirm the high efficiency of the proposed method of information transmission.
