In this paper we investigate the effect of power allocation on the performance of the Distributed Turbo Product Code (DTPC) system. We study the error propagation on distributed coding systems when the relay makes erroneous decisions and present a simple power allocation method to alleviate the effect of relay decoding errors on the iterative decoding at the destination. We validate this method with...
In this paper, we investigate the cooperative communication performance involving space-time block codes (STBC), channel coding, network code and turbo decoding in a wireless Ad-hoc network scenario where two relays are employed for communications from a number of senders to a common sink. To reduce bandwidth and achieve diversity gain, STBC is applied at the two relays. Based on whether network coding...
In this paper, we propose a distributed turbo product code (DTPC) with soft information relaying over cooperative network using block extended bose Chaudhuri Hochquenghem (EBCH) codes as component codes. The source broadcasts extended EBCH coded frames to the destination and to a preassigned relay. After soft-decoding the received sequences and obtaining the log-likelihood ratio (LLR) values, the...
In this paper, we propose a Distributed Turbo Product Code (DTPC) over cooperative network using block Bose Chaudhuri Hochquenghem (BCH) codes as component codes. The source broadcasts extended BCH coded frames to the destination and nearby relays. After decoding the received sequences, each relay constructs a product code by arranging the corrected bit sequences in rows and re-encoding them vertically...
