Description/Abstract

In this paper, we introduce a novel OFDM-aided multifunctional multiple-input multiple-output (MIMO) scheme based on Multi-Set Space-Time Shift Keying (MS-STSK), where the information transmitted over each sub-carrier is divided into two parts, namely the STSK codeword and the implicit antenna combination (AC) index. In MS-STSK, a unique combination of antennas can be activated at each sub-carrier in order to convey extra information over the AC index, while additionally transmitting the STSK codeword. Furthermore, inspired by the MS-STSK concept, this scheme is additionally extended also to the frequency domain in the novel context of our Multi- Space-Frequency STSK (MSF-STSK), where the total number of sub-carriers is partitioned into blocks in order to implicitly carry the block’s frequency index. The proposed MSF-STSK scheme benefits from the huge bandwidths available at mmWaves for partitioning the total number of OFDM sub-carriers into blocks in order to convey more information over the frequency domain. Both proposed systems use STSK codewords as the basic transmission block and they can achieve higher data throughput and better BER performance than STSK. Moreover, given that the system is meant to operate at mmWaves, antenna arrays relying on several antenna elements are employed at both the transmitter and receiver for analogue beamforming (ABF) with the aid of phase shifters and power amplifiers for the sake of overcoming the effect of high path loss.
