Abstract
A transmitter determines a number of available bits (N) in a minimum number of orthogonal frequency division multiplex (OFDM) symbols in which a data field of a packet may fit, by N=(N*(1+U))*ceil(N/(N*R*(1+U))), where Uequals 1 when Space-Time Block Code (STBC) is used and 0 otherwise, where N=LENGTH*8+16, where Nis 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); and determines an integer number of Low-Density Parity-Check Code (LDPCC) codewords to be transmitted, N, and the length of the codewords to be used, L, from information capable of being expressed in a table format.
