A Blind Hammerstein Diversity Combining Technique for Flat Fading Channels

Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...

بهبود دسترسی به کانال در شبکه های محلی بی سیم با تنظیم پویای پنجره‌ی رقابت و فرصت ارسال

Transmission opportunity limit and contention window are two influenced parameters in accessing the media in the networks based IEEE 802.11e standard. In these networks, every wireless station by setting of its contention window value, determines the chance of access to wireless media. Furthermore, a transmission opportunity limit provides a period of transmission without contact for a station....

Offloading over Time-Varying Channels in Wireless Powered Networks

In this work, we consider a network of energy harvesting devices served by an access point with a single antenna that is used for both wireless power transfer (WPT) and information reception. The objective is to maximize the sum throughput of the network over a finite horizon when the channel state information is only available causally. The devices are energized by WPT for a certain duration, ...

A New Method based on Intelligent Water Drops for Multicast Routing in Wireless Mesh Networks

In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...
