Tone-Interleaved Coded Modulation Scheme for MIMO OFDM Communication |
摘要 |
A MIMO OFDM system for TICM is provided. The tone-level interleaver at the transmitter uses a block of NT symbols as its basic unit. This results in different decoding architectures at the receiver. The main advantage of TICM is to merge soft-bit demapping into the Viterbi algorithm. Taking the advantage of the trellis structure inherent in the Viterbi algorithm, TICM can have lower computational complexity and potentially better performance than BICM with the LSD detector and the vector demapper. Although the tone-level interleaving may not have spatial diversity gain, the performance is not affected in 802.11n environments.
