Soft-Decision MLSE Data Receiver for GSM System

Implementation of GSM channel estimation using open-source SDR environment

“…They use various algorithms, but none of them show application of the technique in real time [2], [3]. All the papers are simulation based where the channel is calculated by an algorithm and estimated with another [4]- [6]. This is good for understanding but does not provide details about implementation on over the air signals.…”

“…The received signal will be a convolution of the transmitted training sequence and CIR. Since the central 16 bits of the training sequence is used the matrix 'M' would look like Equation6. Implementing least square estimation to this Implementation Picture matrix and the received signal will give the CIR.…”
