PCM/FM has been widely used in telemetry system. Multiple Symbol Detection (MSD) based signal demodulation methods can achieve lower BER (Bit Error Rate) than other methods. Due to its high computational complexity, current MSD algorithms are implemented in specialized signal processing devices, such as FPGAs (Field Programmable Gate Arrays). As the rapid(More)
Multiple Symbol Detection (MSD) is an important technique in digital signal processing. It estimates the sequence of the received signal by maximum-likelihood principle. Due to its high computational complexity, currently, MSD algorithms were implemented in specialized signal processing devices, such as Field Programmable Gate Arrays (FPGAs). As the rapid(More)
Realizing digital signal demodulation on the general computer is an important research direction in the field of signal processing in recent years. In this paper, the algorithm of BPSK signal demodulation which has high real-time requirements is researched on the general computer. According to the characteristics of “CPU + GPU” heterogeneous computing, the(More)
