Patent ID: 8855142

Claim:
A method implemented by a device for bit padding, for orthogonal frequency division multiplexing (OFDM) transmission, comprising: receiving an unpadded data payload for the OFDM transmission, the unpadded data payload includes service field and tail bits; encoding the unpadded data payload; adding the bit padding to include padded symbols to the encoded data payload, wherein number of padded symbols is computed and based at least upon number of OFDM symbols, even-number tone counts of data tones, and number of media access control (MAC) layer bytes, wherein a number of bits added to the encoded data payload is defined by the equation N pad =N SYM *N SD −( N MACBYTES *8+16+6), wherein N pad comprises the number of bits to be added, N SYM comprises the number of OFDM symbols, N SD comprises the even-number tone counts of data tones, and N MACBYTES comprises the number of bytes in the unpadded data payload; and outputting a minimal number of OFDM symbols.
