Abstract:
We present a simplified 32QAM bit metric calculation method. By dividing the complex plane and merging similar regions, the bit metric is obtained by calculating the distance between the received symbol and a line assigned to each region. Simulation shows that computational complexity in calculating bit metrics is greatly reduced without degrading the performance as compared to the log-MAP and max-log-MAP methods.
Key words: soft demodulation, quadrature amplitude modulation, bit metric, maximum a posteriori
