摘要：

Wireless sensor networks gained a lot of attention in recent years due to their widespread applications. Reliability of data communication and power saving are paramount for applications which use wireless sensor network technology. We propose two classes of short quasi-cyclic LDPC codes suitable for implementation on a resource constrained system. The codes we propose are easy to encode and their decoding performance compares well with random LDPC codes with the same parameters. We implement our codes on a 25mm mote platform provided by Tyndall and compare them with Viterbi coding schemes.
