선형합동 구성법이 적용된 LDPC를 이용한 무선센서네트워크상에서의 에너지 효율의 성능향상

Many wireless sensor networks, typically consists of numerous energy constrained sensor nodes scattered in sensor field. FEC(Forward error correction) gives more energy efficiency end data reliability than system without FEC. LDPC is one of the good code in many FEC code. But generally LDPC code needs more encoding operation than other FEC code by growing their codeword length. In this paper, we adopt Linear-Congruence scheme at generating parity check matrix of LDPC codes to reduce the complexity of encoding process. And then it increase the encoding energy efficiency and ensure the data reliability.
