Abstract :
A receiver structure based on a joint LDPC decoding and synchronization algorithm and realized on an FPGA platform is introduced. The realization system achieves the BER of 1e-5 at the channel SNR of -4.6 dB with moderate hardware complexity, and the performance degradation is less than 1.3 dB from the ideal situation. So it is suitable for deep space communications and other wireless communications.
