Constant Envelope and Coded Modulation for Terrestrial and Satellite Radio. Modems for portable radio terminals must take advantage of state-of-the-art digital communications in order to stay commercially competitive. In particular they need to utilize less bandwidth and power for a fixed data rate. The approach here is to employ a parallel configuration of highly efficient error control codes, together with bandwidth efficient continuous phase modulation (CPM). The theoretical performance of su ....Constant Envelope and Coded Modulation for Terrestrial and Satellite Radio. Modems for portable radio terminals must take advantage of state-of-the-art digital communications in order to stay commercially competitive. In particular they need to utilize less bandwidth and power for a fixed data rate. The approach here is to employ a parallel configuration of highly efficient error control codes, together with bandwidth efficient continuous phase modulation (CPM). The theoretical performance of such a system is to be investigated using a novel information-theoretic technique, and the system will be optimised in terms of coding scheme and CPM complexity.Read moreRead less

Space-time coding for multiple transmit and multiple receive antennas is the enabling technology for future wireless communication systems. Multiple antennas provide independent transmission paths resulting in an increased channel capacity without requiring costly additional bandwidth. Space-time block codes lead to the simplest receiver structures and thus to the most economical solutions.
