Analytical Performance of LDPC Codes with OC in the Presence of Interferers
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 12, Issue 3
Abstract
Optimum Combining (OC) with Low Density Parity-check (LDPC) code improves the performance of overall system (LDPC-OC) by providing additional coding gain. Using Gaussian approximation (GA) approach the bit error rate of LDPC-OC system is derived over an independent and identically distributed (i.i.d) Rayleigh fading channel in presence of interferers. The power of all interferes is assumed to be equal. The analysis is done for the case when the number of interferes is greater than or equal to the number of receiving antenna elements. In this paper, analytical results showed that for a BER of 10-2 and numbers of receiving antennas i.e. N=6, the LDPC-OC system provides an additional coding gain of 6.2 dB over uncoded OC system, thus requires less SNR (Signal to Noise Ratio) and Interference power. Both systems provide diversity gain when the numbers of receiving antennas are increased from 3 to 6.
