Blind symbol Rate estimation in multipath channels

Symbol rate is one of the key values that a receiver needs to know to find out the information contained in the received signal. In situations where the receiver is not aware of this value, it is necessary to use an estimation algorithm to achieve the goal. The subject of this article is "symbol rate estimation in frequency selective multi path channels" that is more complicated than the Gaussian channel. In this article, after studying some of available sources and methods in this field, an algorithm is proposed to estimate the symbol rate in frequency selective multi path channel. The performance of the proposed algorithm has been discussed in the HF and LTE frequency selective channels with bursts contained of 100 symbols. The curves that considered to determine the performance of the algorithm are the percentage of correct estimation and the NMSE graphs. for the channels which the estimator's performance is measured, in the SNR equal to zero decibels, percentage of correct estimation is more than 95% and the NMSE of estimations is almost 0.001.
