In this paper, we demonstrate that multiple concurrent asynchronous and uncoordinated Single-Input Multiple-Output (SIMO) transmissions can successfully take place even though the respective receivers do not explicitly null out interfering signals. Hence, we propose simple modifications to the widely deployed IEEE 802.11 Medium Access Control (MAC) to enable multiple non-spatially-isolated SIMO...

This paper presents closed-form expressions for the ergodic channel capacity of SIMO (single-input and multiple output) wireless systems operating in a Nakagami-m fading channel. As the performance of SIMO channel is closely related to the diversity combining techniques, we present closed-form expressions for the capacity of maximal ratio combining (MRC), equal gain combining (EGC), selection c...

Emerging feature dense portable microelectronic devices pose several challenges, including demanding multiple supply voltages from a single miniaturized power-efficient platform. Unfortunately, the power inductors used in magnetic-based switching converters (which are power efficient) are bulky and difficult to integrate. As a result, single-inductor–multiple-output (SIMO) solutions enjoy popul...

High-speed transmission technologies using array signal processing such as Single Input Multiple Output/ Multiple Input Multiple Output (SIMO/MIMO) have been recently attracted much attention due to smart phones and wireless LAN systems. High data transmission can be realized by utilizing accurate channel state information (CSI). However, it is well known that the characteristic of SIMO/MIMO pe...

The inverse scattering problem with point scatterers and the single-input-multipleoutput (SIMO) measurements is analyzed by the compressed sensing techniques with and without the Born approximation. Three main results about (probabilistic) recoverability of sparse target by the L-optimization technique called Basis Pursuit (BP) are obtained in the high frequency limit. In the absence of noise, ...

This contribution considers nonlinear space–time equalisation (STE) for multiple receive-antenna induced single-input multipleoutput (SIMO) systems. By exploiting the inherent symmetry of the underlying optimal Bayesian STE solution, a novel symmetric radial basis function (RBF) based STE scheme is proposed, which is capable of approaching the optimal Bayesian equalisation performance. Adaptive...

In this work, low-complexity suboptimum detectors have been analyzed for a single-input multiple-output (SIMO) direct-sequence code division multiple access (DS/CDMA) system. As a contribution, a hybrid multiuser detector based on polynomial expansion (PE-MuD) with alpha-estimation determined by Gerschgorin circles Theorem (GCT), and followed by a lowcomplexity local search procedure is propose...

This paper investigates a blind space–time equaliser (STE) designed for single-input multiple-output (SIMO) systems that employ high-throughput quadrature amplitude modulation schemes. A constant modulus algorithm (CMA) aided soft decision-directed (SDD) scheme, originally derived for low-complexity blind equalisation of single-input single-output channels, is extended to the SIMO scenario. Sim...

In this paper, we demonstrate that multiple concurrent asynchronous and uncoordinated Single-Input MultipleOutput (SIMO) transmissions can successfully take place even though the respective receivers do not explicitly null out interfering signals. Thus motivated, we propose simple modifications to the widely deployed IEEE 802.11 MAC to enable multiple nonspatially-isolated SIMO sender-receiver ...

Modern mixed-signal SoCs integrate a large number of sub-systems in a single nanometer CMOS chip. Each sub-system typically requires its own independent and wellisolated power supply. However, to build these power supplies requires many large off-chip passive components, and thus the bill of material, the package pin count, and the printed circuit board area and complexity increase dramatically...
