In the conditions of limited frequency resource and along with increasing requirements towards transmission data rates in radio communications systems a demand for increasing their spectral characteristics arouses. One of technologies increasing the channel capacity by many times (compared to traditional radio communications systems with one transmitting antenna) is the space-time encoding technique. The absence of effective signal processing algorithms, having acceptable computational complexity, at the receiving side appears to be limiting factor for systems with space-time encoding. A new algorithm for demodulating signals with space-time encoding, which exceeds the known algorithm in interference immunity and possesses moderate computational complexity, is suggested.
