| Abstract(in English) | This paper proposes an iterative channel estimation scheme for trellis coded soft interference canceller followed by MMSE filter (TC-SC/MMSE), which is comprised of trellis coded modulation (TCM) and iterative SC/MMSE equalizer, to achieve much higher accuracy than conventional channel estimation techniques. In the proposed system, after the channel impulse response is measured using a preamble sequence, it is also updated in iterative manner using a part of reliable log-likelihood ratio (LLR) sequence of the TCM soft-input soft-output (SISO) decoder to further improve accuracy of the estimated channel impulse response. Computer simulation confirms that the proposed scheme is effective in improvement of the channel estimation accuracy. |
