Abstract |
|
|
| This paper studies the problem of detection for orthogonal frequency domain multiplexing (OFDM) systems over rapidly
time varying multipath channels. A new adaptive successive detection method, which uses the information provided by all of the
received symbol, and the band structure of the frequency domain channel matrix, is proposed. The new scheme can get the similar
performance as the maximum likelihood sequence estimation (MLSE) withmuch lower complexity. It can alsomake a trade-off between
the performance and complexity adaptively. Simulation results demonstrate the merits of the proposed algorithms over traditional ones. |
