The channel capacity of a MIMO telecommunication system depends on different parameters such as the signal-to-noise ratio, the space-time characteristics of the propagation channel, the antenna array geometry and the antenna pattern. However, the propagation channel remains the strongest constraint imposed on designers of new radio air interfaces. Using a MIMO channel model, computer simulations are...
This paper is focused on the study of layered space-time-frequency (LSTF) architectures with channel coding for orthogonal frequency division multiplexing (OFDM) multiple-input multiple-output (MIMO) multiplexing systems for high speed wireless communications over a frequency-selective fading channel. In order to achieve the available spatial, temporal and frequency diversities, and also make the...
In this paper, we propose a parallel hybrid merge-select sorting approach for the implementation of K-best list sphere detection (LSD) multi-input multi-output (MIMO) decoder based on a recently developed novel Reconfigurable Instruction Cell Array (RICA). Several popular sorting algorithms adopted in MIMO decoding are analyzed and mapped onto our proposed platform. We discuss the targeted K-best...
A Hybrid Antenna Selection (HAS), also called Soft Antenna Selection (SAS), method is basically implemented by a Linear Network (LN) which is located in RF domain of Multiple Input Multiple Output (MIMO) systems. In this paper, we evaluate the SAS-MIMO system, which is optimally tuned based on spatial multiplexing/diversity transmissions, in terms of receiver sensitivity issue. To this end, a SNR...
High data-transmission rate and reliable communication in shallow water is a challenge for underwater acoustic (UWA) communication. With spatial and temporal focusing characteristics, time reversal processing (TRP) can be used for multiple input/multiple output (MIMO) UWA communication. In combination with adaptive channel equalization and channel coding methods, TRP can further reduce the residual...
