Patent ID: 8842749

Claim:
An orthogonal frequency division multiplexing (OFDM) multiband transmitter adapted to perform multiple-subcarrier-joint-modulation (MSJM) precoding, comprising: a bit interleaver for interleaving a bit block independently from each other bit block preceding and subsequent to said bit block, wherein the bit block and said each other bit block are included in a plurality of bit blocks, each bit block arranged from I encoded information bits, and said bit interleaver for grouping the I interleaved bits of the bit block into p different bit groups, wherein each bit group includes k interleaved bits and wherein p, k, and I are positive integers that satisfy the relationship that I is equal to p×k; a symbol mapping unit for mapping, for each of the p bit groups of the bit block, the k bits associated with the bit group to m symbols according to a MSJM scheme; and a symbol interleaver for allocating the m×p symbols for the bit block to n data subcarriers of s consecutive OFDM symbols, wherein m, n, and s are positive integers that satisfy the relationship that s is equal to (m×p)/n.
