Kurzfassung
In this paper, we consider a transmission system employing orthogonal frequency division multiplexing~(OFDM) with bit-interleaved coded modulation and imperfect channel state information at both transmitter and receiver. An adaptive bit loading scheme in combination with cyclic delay diversity and discontinuous Doppler diversity is proposed at the transmitter. The loading procedure minimizes the bit-error rate at the decoder output, and the transmit diversity schemes mitigate channel correlations. We present the achievable gains.
