abstract = "This paper provides the performance of the BCH and LDPC codes applied as forward error control (FEC) to GPS CNAV2 and makes a new proposal. We first investigate the performance of 2 LDPC codes and confirm that some UEP is applied. Since these two codes are combined by some interleaver, and hence they cannot be decoded unless both codewords are received. Therefore we propose to use another single LDPC codes of longer length which is equal to the sum of two lengths of these shorter LDPC codes. By investigating the performance of all these three LDPC codes, we confirm that the proposed longer length LDPC codes are better than the overall performance of 2 shorter LDPC codes by 0.4 dB at FER=   ."
