Transceiver design for SU-MIMO system with improper modulations using per antenna power constraint and perfect CSI

Abstract

This paper addresses the problem of joint transceiver designs for single user-Multiple-input and Multiple-output system(SU-MIMO) employing one dimensional improper modulations such as binary phase shift-keying and M-ary amplitude shift-keying(M-ASK) using per antenna power constraint. Conventionally, most of the transceiver designs are based on the sum power constraint (SPC).However, in practical SPC is not realistic as it does not take into account of power constraint of an individual power amplifier. To solve this problem, under perfect CSI, per antenna power constraint is formulated into an optimization problem giving a novel joint linear transceivers that minimizes the mean square error at the output of the decoder. The simulation results show that the proposed scheme has a near-optimum performance considering practical constraints.

Design of Secure and Reliable MU-MIMO Transceiver System for Vehicular Networks

“…This makes the system fail to meet the practical requirements and makes its challenging to be realized in real-time. An SU-MIMO transceiver has been proposed with 1-D improper modulation and PAPC [19] to meet the practical requirements in point-to-point communication. This has been extended for MU-MIMO uplink transceiver system.…”
