Abstract :
Error coded modulation is considered with focus on mobile radio. A new scheme, namely multilevel coded modulation with independent decoding on levels, and some attractive derivatives (coding based on multiple classes of levels) are introduced. A comparison of the new coded modulation schemes and well-known methods is performed by simulations on both static and interleaved Rayleigh fading channels. It is shown that the new schemes provide high power efficiency independent of the channel situation, and outperform the prior art methods in this context. The robustness to channel variations is the key feature which make the new scheme attractive for mobile radio systems
