N2 - Increased SNR and Reduced BER is being the aim of wireless CDMA systems. Coding plays a major role in achieving the target. LDPC codes are being the desired ones in achieving reduced area and power input. This paper presents a high performance error detection and correction for non-binary low density parity check codes (LDPC). Check node processing is formulated by using Euclidean graph decoding architecture. The proposed decoding method reduces the number of iterations and achieves reduction in area and power. EG-Decoder with Q-ary sum product algorithm is implemented in log domain and reduced power of 0.6080 mW and area of 2.17 MB is achieved.
