Low-Complexity Geometry-Based MIMO Channel Simulation

The simulation of electromagnetic wave propagation in time-variant wideband multiple-input multiple-output mobile radio channels using a geometry-based channel model (GCM) is computationally expensive. Due to multipath propagation, a large number of complex exponentials must be evaluated and summed up. We present a low-complexity algorithm for the implementation of a GCM on a hardware channel s...

Low-complexity Mimo Channel Simulation by Reducing the Number of Paths

The simulation of frequency-selective multiple-input multipleoutput (MIMO) channels is computationally expensive. Especially on a real-time simulation platform the number of paths that can be realized is limited by the available processing power. This paper presents a new algorithm, that reduces the number of paths in the channel impulse responses while preserving the original power delay profi...

Low-Complexity and Basis-Free Channel Estimation for Switch-Based mmWave MIMO Systems via Matrix Completion

Recently, a switch-based hybrid massive MIMO structure that aims to reduce the hardware complexity and improve the energy efficiency has been proposed as a potential candidate for millimeter wave (mmWave) communications. Exploiting the sparse nature of the mmWave channel, compressive sensing (CS)-based channel estimators have been proposed. When applied to real mmWave channels, the CS-based cha...

Low Complexity Tree Searching-Based Iterative Precoding Techniques for Multiuser MIMO Broadcast Channel

In this letter, we propose two computationally efficient precoding algorithms that achieve near-ML performance for multiuser MIMO downlink. The proposed algorithms perform tree expansion after lattice reduction. The first full expansion is tried by selecting the first level node with a minimum metric, constituting a reference metric. To find an optimal sequence, they iteratively visit each node...

Low complexity MIMO detection algorithm

The multi antenna systems offer a much larger channel capacity than the traditional single antenna systems. The price which has to be extra paid is detection complexity. In this paper we examine performance of the low complexity algorithm called zero forcing–maximum likelihood (ZFML) [5]. We find this algorithm appropriate for MIMO (Multiple Input Multiple Output) systems using more receive tha...
