Abstract :
Single-carrier block transmission is an alternative scheme to orthogonal frequency-division multiplexing for wireless communications when a low peak-to-average power ratio is needed for transmit power efficiency. In this paper, the receiver structure and performance are discussed for single-carrier block transmission with cyclic prefix. As the wireless transmission is over doubly selective channels, a basis expansion model is used to capture both time and frequency-selectivity of the channel. The receiver estimates the channel coefficients in the time domain and uses the channel estimates for equalization in the frequency domain. The channel estimation is assisted by time-domain pilot insertion. The structure of the frequency-domain channel matrix is exploited and a linear minimum mean-square error equalizer is used for equalization. When the basis expansion model is chosen such that it well matches the true channel, simulation results show good receiving performance of the proposed algorithm in a mobile broadband communication scenario.
