| Abstract: | We present an unequal decoding power allocation(UDPA) approach for minimization of the receiver power consumption subject to a given quality of service(QoS),by exploiting data partitioning and turbo decoding.We assign unequal decoding power of forward error correction(FEC) to data partitions with different priority by jointly considering the source coding,channel coding and receiver power consumption.The proposed scheme is applied to H.264 video over additive white Gaussion noise(AWGN) channel,and achieves ... |
