Reducing Cyclic Prefix Overhead Based on Symbol Repetition in NB-IoT-Based Maritime Communication
文献摘要：
With the increasing maritime activities, a great demand of wide-area maritime digital data ser-vices is needed. Therefore, Narrowband Internet of Things (NB-IoT) that can provide wide coverage has been expected as an application for maritime commu-nication networks (MCNS). In this paper, we aim to enhance the spectral efficiency in NB-IoT by reducing the cyclic prefix (CP) overhead in random access sig-nal without causing interference. The key point of the proposed scheme is the symbols transmitted for multi-ple times repeatedly in NB-IoT. Specifically, all CP are removed and multi-path fading effect is eliminated by using a repeated symbol to cover the disturbed sym-bol to construct a circular convolution structure of the channel with the same effect as adding CP. In addition, a single-tap equalization is still appropriate. To vali-date the effectiveness of the proposed scheme, simula-tion results are carried out with respect to the bit error ratio (BER).
