  Abstract

This paper presents LDPC codes' upper bounds over the waterfall　SNR　region. The previous researches have focused on the average bound or ensemble bound over the whole SNR　region and showed the performance differences for the fixed block size. In this paper, the particular LDPC codes' upper bounds for various block sizes are calculated over the waterfall SNR region and are compared with BP decoding performance. For different block sizes the performance degradation of BP decoding is shown.
