Error Control Coding Scheme Based On 60GHz Inter-chip Wireless Interconnection System

In order to solve reliability problem caused by burst errors in 60GHz inter-chip wireless interconnection system, different error-control coding (ECC) schemes is studied in this system. According to features within 60GHz short-range communication system, the CM7 channel characteristics and fading channels signal-to-noise ratio (SNR) are analyzed for this scene. On this basis, combined with error-control coding theory, the bit-error-rate (BER) performance with the application of Hamming codes and Convolution codes are analyzed and Monte Carlo simulations are achieved. For different coding gain,SNR environment and maximum communication distance of Convolution codes, the priority coding scheme is given. It provides the technical reference of ECC which applied to 60GHz inter-chip wireless interconnection system.
