Abstract :
Block coded modulation (BCM) and multiple BCM (MBCM) combined with an unconventional signal partition are proposed to produce unequal error protection (UEP). The presented BCM and MBCM have the advantage of allowing Viterbi decoding. By increasing the minimum squared Euclidean distance (MSED) and reducing the nearest-neighbor signal sequences, the bit error rate (BER) for important bits is greatly reduced
