Space-Time Uplink Transmission in Non-Coherent Systems With Receiver Having Massive Antennas

IEEE Communications Letters, 2017
In this letter, an uplink communication scenario in which one dual-antenna transmitter communicates with a receiver having massive antennas is considered. We propose a $2\times 2$ space-time transmission scheme, which does not require any knowledge of instantaneous channel state information at either transmitter or receiver.

Time-Hopping M-Walsh UWB transmission scheme for a one-bit non-coherent receiver

2010 7th International Symposium on Wireless Communication Systems, 2010
We propose a Time-Hopping (TH) M-ary Walsh transmission scheme using a one-bit non-coherent receiver for power efficient and low complexity low data rate Ultra Wideband (UWB) communications. The analytical Bit Error Rate (BER) bounds of the M-Walsh modulation and the widely used M-ary Pulse Position Modulation (M-PPM) are derived and validated in the ...

Dual Decomposition Based Power Allocation for Downlink OFDM Non-Coherent Cooperative Transmission System

2012 IEEE 75th Vehicular Technology Conference (VTC Spring), 2012
In this paper, we study the subchannel power allocation problem to maximize the total throughput of the downlink orthogonal frequency division multiplexing (OFDM) multiple access points (APs) systems with non-coherent cooperative transmission. Although the problem has been claimed as a non-convex optimization problem, we prove that the duality gap ...
