Abstract

In scenarios where channel state information is available to the receiver, making use of the information in detection significantly improves system performance. Such transmission scheme is called coherent detection. In this work, we propose a new family of space-time codes for coherent detection schemes in a wireless environment using multiple transmitter and receiver antennas. The decoding problem can be efficiently solved by parallel sphere decoder algorithm. A combination of Genetic algorithms and stochastic gradient descendent algorithms is established for the code optimization. Our simulation results indicate that such a wireless communication technique is suitable for sensing systems with reliable transmission of high volume of data.
