摘　　要：Turbo乘积码(TPC)用于无线数据传输领域,可对无线传输数据进行纠错,在遥测数据传输领域应用较多。该算法具有较好的抗干扰和抗衰落特性,是一种高效的纠错编码技术。信道编码算法的实现一般需要发射机在发射时进行信道编码,接收机进行信道解码,当接收机不具备信道解码功能时,也可以接收无线数据,只是无法对数据进行纠错和解码。本文采用软件实现了一种事后TPC译码算法,利用该算法可对普通遥测接收机(不具备TPC译码功能)接收到的数据文件进行TPC译码,也可以实时接收数据并解码输出,若普通遥测接收机集成该软件,则具备了TPC译码功能,即可实现遥测数据纠错传输,提高遥测数据质量。Turbo product codes(TPC)are used in wireless data transmission,which can correct errors in wireless data transmission and are widely used in telemetry data transmission.The Algorithm has good anti-jamming and anti-fading characteristics,and is an efficient error-correcting coding technique.The realization of the channel coding algorithm generally requires the transmitter to encoding and the receiver to decoding.When the receiver does not have the decoding function,it can also receive the wireless data,but the data can not be corrected and decoded.In this paper,A TPC decoding algorithm is implemented,which can be used to decode the data files received by ordinary telemetry receiver(without TPC decoding function),it can also receive the data in real time and decode the output.If the general telemetry receiver integrates this softeware,it has the TPC decoding function,which can realize the telemetry data error correction transmission and improve the telemetry data quality.
