Noiseproof improvement using 2M-orthogonal space-time coding
Abstract
This article presents a technique of simple transmit diversity, that improves receive signal quality using two-branch transmit antennas. In 1998 Alamouti first suggested the method of coding, which explores a full diversity order combining with linear decoding process on the receive side. Alamouti diverse transmit system improves a bit-error-rate ratio, rises a transmit speed or expands a channel capacity of wireless system. As a result of science research founding this article, a new unified approach of space-time coding technique has been developed. Taking this approach it is possible to build 2M-branch transmit systems with one receive antenna for decreasing the dimension of cluster in multicell networks with constant noiseproof of the radio system.
