Abstract

In this article, we present multiple-input receiver architecture for MIMO (Multiple-Input Multiple-Output) wireless communication applications. The proposed implementation is provided by a defined number of identical receiver units that are fed by a RF modulated signal on specific carrier frequency, power strength and initial phase. These units carry out the corresponding amplification, filtering and demodulation procedures. Details on design and implementation of this Printed-Circuit-Board are introduced and further discussed. Experimental results are also presented, allowing the validation of investigation on the performance of the current receiver architecture. Besides, these measurements indicate that the proposed device, combining with a suitable antenna array, provides a versatile receiver platform for baseband signal processing. The incoming RF modulated signals have frequencies on the range of 2.4 GHz, several phases, magnitudes and modulation modes. From these, it seems that the proposed receiver implementation supports MIMO communication and multiple port channel characterization applications at 2.4 GHz ISM (Industrial, Scientific and Medical) band.

Summary

Introduction

Modern wireless communication systems continue to push for wider bandwidth capabilities, higher data rates and better quality of services. Appropriate synchronization and data acquisition procedures have to be supported by this device in order to collect and record the data transmission streams from each sub-channel at any scattering radio propagation environment. The efficiency of such systems depends on several performance and channel parameters. Frequency, code division multiplexing and hybrid methods are mainly used in these applications [4,5] These devices improve MIMO system performance and offer crucial assumptions that provide a resource for channel model developments. Existing experimental measurements set-ups are usually not able to probe a number of parallel streams, simultaneously This feature is crucial for MIMO channel characterization and communication applications.
