摘要： A method of concatenation for LDPC encoding in an OFDM wireless system selects codewords based on the data packet payload size, wherein the payload size is the number of transmitted information bits in octets. For low transmission rates, shortening and puncturing across all codewords within the packet is applied to minimize OFDM symbol padding. For high transmission rates, only shortening across all codewords within the packet is applied to minimize OFDM symbol padding.

摘要： An improved LDPC encoding with concatenation rule and code size with packet lengths specified in octets is provided. The LDPC block size is selected to be an integer number of OFDM tones. The concatenation rule is an improvement of the shortening and puncturing scheme for low data rate. The improvement is two fold. First, the code length is selected based on the number of transmitted information bits in octets (HTLENGTH). Second, it is determined whether one extra OFDM symbol padding should be added based on the number of shortening bits in the last codeword and the available padding bits in the last OFDM symbol.
