Abstract: "Block-based single-carrier cyclic prefixed"(SC-CP) modulation is an alternative to "orthogonal frequency division multiplexing" (OFDM), offering a lower peak-to-average power ratio (PAPR), more robustness against carrier frequency offset and against spectral nulls. To shorten the guard interval in block-based single-carrier modulation, a zero-inserting precoder and a two-stage linear equalizer scheme has been proposed by Song, Fung, Wong, Meng & Tseng in [1]. That proposed scheme is applicable even without any cyclic-prefix (CP). However, that scheme assumes that the channel impulse response is perfectly known, which is not the case in most real world systems. In practice, because of the imperfect channel estimation and channel variation over time, there is deviation in the magnitude and/or phase of the channel impulse between the presumed prior knowledge and actuality. This dissertation investigates how the zero-inserting precoder and a two-stage linear equalizer scheme in [1] would be degraded, in terms of its bit error rate (BER) when such channel mismatch exists. This work had already been published in the 2012 Conference on Photonics and Communications [2]. The formal acceptance letter is shown in Appendix.
