Non-coherent quantum multiple symbol differential detection for wireless systems

When using an MSDD, the detection of a user’s symbols is performed over windows of differentially modulated symbols, hence they exhibit an increased complexity with respect to the Conventional Differential Detector (CDD), while simultaneously improving the performance of the system, especially at high Doppler frequencies

Abstract

In large-dimensional wireless systems, such as Cooperative Multi-cell Processing (CoMP), mm-Wave and massive MIMO systems, or cells having a high user density, such as airports, train stations and metropolitan areas, sufficiently accurate estimation of all the channel gains is required for performing coherent detection. Therefore they may impose an excessive complexity. As an attractive design alternative, differential modulation relying on non-coherent detection may be invoked for eliminating the requirement for channel estimation at the Base Station, although at the cost of some performance degradation. In this treatise we propose low-complexity Hard-Input Hard-Output (HIHO), Hard-Input Soft-Output (HISO), as well as Soft-Input Soft-Output (SISO) Quantum-assisted Multiple Symbol Differential Detectors (QMSDD) which perform equivalently to the optimal, but highly complex Maximum A posteriori Probability (MAP) MSDDs in multi-user systems, where the users are separated both in the frequency domain and in the time domain. When using an MSDD, the detection of a user’s symbols is performed over windows of differentially modulated symbols, hence they exhibit an increased complexity with respect to the Conventional Differential Detector (CDD), while simultaneously improving the performance of the system, especially at high Doppler frequencies
