An Improved Joint Data Rate and SNR Estimation
Shengbo Hu, Meng Xin, Yao Xiujuan, Na Zhao · 2007
Knowledge of data rate is required to carry out maximum-likelihood detection of other parameter, such as the carrier phase or modulation type. In this paper, we introduce an improved algorithm of joint SNR and data rate estimation in absence of symbol-timing error. The algorithm is a GLRT-type modification to the method described in section 2. To compare the algorithm, performance metrics are presented. Simulation results show that algorithm in section 2 outperforms the proposed algorithm for the higher data rates, but fails to do so for the lower ones.
