Low-complexity multi-symbol detection algorithm for telemetry PCM / FM signal

针对遥测PCM/FM信号解调中多符号检测(MSD)算法存在的计算复杂度高、工程实现难度大等问题,提出了一种低复杂度MSD算法。该算法通过利用分段相关等效较长的相关来降低算法复杂度。仿真结果表明,该算法在损失较小性能的前提下,显著降低了MSD算法计算复杂度,易于硬件实现,实用性强。

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 cor- relation 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.
