As the demand for communications via satellite is rapidly increasing, techniques that produce large traffic capacity are becoming more and more appreciated. We present a class of block coded modulation (BCM) and multiple block coded modulation (MBCM) schemes in this paper. While the BCM scheme is directly derived from our previous work, the MBCM schemes are newly developed using a technique of multiple symbol transmission via a single trellis branch. This class of BCM and MBCM schemes is both power and bandwidth efficient. They also have an advantage in holding both a trellis and a block structure. Code structures, decoding trellises and the corresponding branch variables of these BCM and MBCM schemes are all derived. Their applications to satellite communications are discussed. Computer simulations are performed to verify coding gain performance.
