Binary source estimation using indirect observation by a cluster of wireless sensors in a two-tiered architecture is considered. The high correlation among sensors' observation is exploited in order to implement an efficient distributed Joint Source Channel Coding (DJSCC) scheme based on Parallel Concatenated Convolutional Codes (PCCC). A novel approach employing two sink nodes per cluster providing...
In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
