New Receivers in Digital Communications, Performance Evaluation and Comparisons

Abstract

Recently developed STTS-MF receiver by the authors in^1,2 (referred as TTS-MF receiver in^1,2) performs better than the traditional Matched Filter based receiver (referred as STS-MF receiver in^1,2), but only when the <i style="mso-bidi-font-style:normal">SNR </i>(expressed in <i style="mso-bidi-font-style:normal">dB</i>) is positive. In this paper, we introduce a new receiver, the CTTS-MF receiver, and demonstrate that it performs better than both STTS-MF and STS-MF receivers, for both positive and negative <i style="mso-bidi-font-style:normal">SNR </i>(expressed in <i style="mso-bidi-font-style:normal">dB</i>) values, for the correlated digital signals known as, the <b style="mso-bidi-font-weight:normal"><i style="mso-bidi-font-style:normal">p-q</i></b> signals. Comparisons and relative advantages of the CTTS-MF and the STTS-MF receivers are illustrated by extensive simulation study with baseband communications as example domain.
