Performance Analysis of Channel Assignment Scheme in Wimax

Performance analysis of a channel assignment scheme in cellular communication systems

In cellular communication systems, channel assignment schemes are very important to improve teletraf®c performance characteristics. Because of the overlapping design of the cells in cellular communication systems, a mobile user is capable of communicating with two different bases. In this paper, a new channel assignment scheme is proposed to improve the blocking probability of a cellular commun...

Improving QoS Performance of Multi-radio Multi- channel WMNs by Adopting a Novel Channel Assignment Scheme

The CSMA/CA based random channel access mechanisms in Wireless Mesh Networks(WMNs), IEEE 802.11 DCF and EDCA, are inefficient to eliminate effectively hidden terminal and exposed terminal problems in multi-hop scenarios. In this paper, we propose efficient channel assignment and routing protocols for multi-radio multi-channel (MRMC) wireless mesh networks. These set of protocols are based on La...

Performance Analysis of a Joint Space-Time Block Codes and Channel Estimation Scheme in DL-PUSC Mode of Mobile WiMAX

Mobile WiMAX has emerged as a starting point of broadband mobile wireless era. Besides plenty of advantages over the prior systems, it also utilizes multiple-antenna techniques to improve the transmission quality. Although this approach has been intensively studied, there are just few published works taking into account channel estimation to obtain realistic performance. This paper studies a jo...

Performance Evaluation of Physical Layer of Mobile WiMAX System by Implementing Hybrid Channel Coding Scheme

The demand of wireless communication is high data rate along with error free communication. An error in communication can be reduced by employing proper channel coding techniques. In this paper, authors have proposed the hybrid channel coding scheme in which convolution codes and turbo codes are combined to perform together. This scheme helps to provide smooth communication with high data rate ...
