Abstract

In this paper, we propose a novel autocorrelation receiver (AcR) for transmitted-reference signaling that alleviates excessive noise collection. Specifically, we employ a stop-and-go strategy based on energy detection in the AcR to selectively collect portions of effective signal. This avoids noise collection from time regions within the integration interval that do not contain useful energy contributions. To gain insight into the impact of noise and energy collection on system performance, we propose a semi-analytical approach to evaluate the bit error rate. Numerical results highlight the potential performance gain that can be obtained by our proposed scheme at the expense of a small increase in complexity.
