Performance Analysis of cdma2000 Wireless Standard Error Correcting Codes

Third Generation Partnership Project-2 proposed cdma2000 standards, which offers two error correcting coding techniques, Convolutional Codes and Turbo Codes. In this paper we analyze the encoding and decoding techniques of the convolutional codes of cdma2000 standards. The performance, in the form of BER (Bit Error Rate) vs. 0 / b E N (bit energy per noise spectral ratio), by varying code rate, frame size, number of decoding iteration of the standardized turbo codes is shown. It is found that if architectural components of turbo codes is changed, not only the BER performance but also the decoding delay and throughput are changed. Results, presented in this paper, facilitate the service provider to trade off among delay, throughput and BER performance as per its requirement.
