Node Throughput Analysis of Decentralized Wireless Networks Using Multibeam Antennas in Multipath Environments

The use of multibeam antennas (MBAs) in decentralized wireless networks significantly increases the throughput by improving spatial reuse and extending coverage compared with single-beam antennas. The throughput performance may, however, degrade in multipath environments due to the fact that multipath propagation increases the probability of collision among different users. Based on the probabi...

Accurate Techniques to Evaluate Cdma Bit Error Rates in Multipath Channels with Imperfect Power Control

In this paper, a Simplified Expression for the Improved Gaussian Approximation (SEIGA) is presented for accurately evaluating Direct Sequence Code Division Multiple Access (DS-CDMA) bit error rates in multipath channels and systems with imperfect power control. Previous techniques for evaluating bit error rate performance of these systems can lead to overly optimistic results under a variety of...

Transmitter-Side Antennas Correlation in SVD-assisted MIMO Systems

MIMO techniques allow increasing wireless channel performance by decreasing the BER and increasing the channel throughput and in consequence are included in current mobile communication standards. MIMO techniques are based on benefiting the existence of multipath in wireless communications and the application of appropriate signal processing techniques. The singular value decomposition (SVD) is...

Spectral efficiency of FDMA/TDMA wireless systems with transmit and receive antenna arrays

In recent years, the ever growing need for higher capacity in wireless systems has fueled the interest in exploiting the spatial dimension—through the use of antennas arrays—to improve the utilization of the available radio spectrum. As a result, a large number of space–time techniques have been proposed wherein arrays are used to mitigate interference and enhance signal levels. More recently, ...

Experimental Analysis of RSSI-Based Indoor Location Systems with WLAN Circularly Polarized Antennas

Circularly polarized antennas are used in 2.4 GHz ZigBee radio modules to evaluate performance improvement of RSSI (Received Signal Strength Indicator) based location techniques, with respect to conventional linearly polarized antennas. Experimental RSSI measurements in an indoor environment clearly show that multipath fading is significantly reduced when CP antennas are used; this determines a...
