Research Data: Joint Quantum-Assisted Channel Estimation and Data Detection

Abstract

This DOI contains the datasets of Figures 6-20 of the paper titled Joint Quantum-Assisted Channel Estimation and Data Detection. Each folder is named according to the corresponding figure, where the dataset of each curve is stored in a .dat file. To regenerate the figures please use the command "gle Figure_Name.gle" (Graphics Layout Engine -GLE- should be installed on your machine). Each folder already includes the generated color and grayscale versions of the figures. Paper Abstract: Joint Channel Estimation (CE) and Multi-User Detection (MUD) has become a crucial part of iterative receivers. In this paper we propose a Quantum-assisted Repeated Weighted Boosting Search (QRWBS) algorithm for CE and we employ it in the uplink of MIMO-OFDM systems, in conjunction with the Maximum A posteriori Probability~(MAP) MUD and a near-optimal Quantum-assisted MUD (QMUD). The performance of the QRWBS-aided CE is evaluated in rank-deficient systems, where the number of receive Antenna Elements (AE) at the Base Station (BS) is lower than the number of supported users. The effect of the Channel Impulse Response (CIR) prediction filters, of the Power Delay Profile (PDP) of the channels and of the Doppler frequency have on the attainable system performance is also quantified. The proposed QRWBS-aided CE is shown to outperform the RWBS-aided CE, despite requiring a lower complexity, in systems where iterations are invoked between the MUD, the CE and the channel decoders at the receiver. In a system, where U=7 users are supported with the aid of P=4 receive AEs, the joint QRWBS-aided CE and QMUD achieves a 2 dB gain, when compared to the joint RWBS-aided CE and MAP MUD, despite imposing 43% lower complexity.
