We propose a design of block-shifted pilot scheme for the multipair massive multiple-input multiple-output (MIMO) relaying system. The proposed scheme balances the tradeoff between pilot transmission overhead and channel estimation accuracy in scenarios with limited length of coherence time interval, and thereby the system performance is dramatically(More)
In this paper, we focus on the positioning of an unknown radio interference source (RIS) in cellular networks. To locate the unknown RIS in the current cellular system-s without modifying existing base station (BS) structure, we propose a novel positioning scheme based on received signal strength (RSS) information at the BS antenna ports. To solve the(More)
—We propose a pilot-data transmission overlay scheme for multipair massive multiple-input multiple-output (MIMO) relaying systems employing either half-or full-duplex (HD or FD) communications at the relay station (RS). In the proposed scheme, pilots are transmitted in partial overlap with data to decrease the channel estimation overhead. The RS can detect(More)
—Transmitted reference pulse cluster (TRPC) was recently proposed for low data rate ultra-wideband (UWB) communications due to its robust performance, higher data rate, enhanced reliability and lower implementation complexity compared to the conventional transmitted reference technique. In this paper, we study bi-directional cooperative relay strategies for(More)
