Patent ID: 7664008

Claim:
A method, comprising: determining, by a processor, a number of available bits (N avbits ) in a minimum number of orthogonal frequency division multiplex (OFDM) symbols in which a data field of a packet may fit, in accordance with N avbits =( N CBPS *(1 +U STBC ))*ceil( N pld /( N CBPS *R *(1 +U STBC ))), where U STBC equals 1 when Space-Time Block Code (STBC) is used and 0 otherwise, where N pld =LENGTH*8+16, where N CBPS is the number of coded bits per symbol, where R is the code rate, and where LENGTH is a number of bytes in a Physical Layer Convergence Protocol (PLCP) PLCP Service Data Unit (PSDU); determining, by the processor, an integer number of Low-Density Parity-Check Code (LDPCC) codewords to be transmitted, N CW , and the length of the codewords to be used, L LDPC , from information expressible in a Table format and comprising: LDPC codeword N avbits Number of LDPCC length L LDPC range (bits) codewords N CW (bits) N avbits ≦ 648 1 648 648 < N avbits ≦ 1296 1 1296 1296 < N avbits ≦ 1944 1 1944 1944 < N avbits ≦ 2592 2 1296 2592 < N avbits ceil ⁢ ⁢ ( ( LENGTH × 8 + 16 ) ( 1944 × R ) ) 1944; and outputting, by the processor, the determined integer number of LDPCC codewords to be transmitted and the length of the codewords to be used.
