碩士 === 逢甲大學 === 通訊工程學系 === 101 === We propose a cyclic prefix free multiple-access frequency-domain equalization systems in ultra-wideband communications. Relying on designed procoding matrices imposed on the transmitted data and designed decoding matrices adopted at the receiver, the resultant multiple-access interference and interblock interference free relationship is structured by block circulant channel matrices. Thanks to the block circulant structure; both FFT and IFFT operations are introduced to simplify the matrix inversion at the receiver so that the desired transmitted data can be estimated and then detected. We also analyze and discuss the pairwise error probability of the proposed schemes. Simulation results are used to demonstrate the performance of the proposed method.
