There are deficiency such as high computational complexity and engineering issues in multi-symbol detection (MSD) algorithm for telemetry PCM/FM signal. This paper presented a lower complexity algorithm exploiting segmentary correlation to equivalent the correlation . Simulation results show that this algorithm greatly lower the computational complexity with minus performance loss. It can be concluded that this algorithm is more practical and easily implemented for engineering.
