Abstract :
This paper presents the application of Low-Density Parity-Check (LDPC) codes in Ka band. Considering the weather impairments and multi-path fading in Ka band, the channel model and system model have been found. We analyzed the Bit error rate (BER) performance of LDPC codes compared with convolutional code (CC) and uncode at 16 QAM and BPSK modulation technique. The results show that LDPC codes give the best performance. In the case of 16 QAM or BPSK LDPC codes can provide 2.5 dB or 2.6 dB coding gain compared with CC at a BER of 10-3, and LDPC codes can provide 2.9 dB coding gain compared with CC at a BER of 10-4. It is show that LDPC codes in Ka band are effective and feasible.
