The performance of multi-code systems is limited by inter-channel-interference (ICI) resulting from the multipath effect in the radio channel. In order to lower the error floor, advanced processing techniques, similar to the multiuser detection methods, may be implemented in the receiver. In this paper an adaptive MMSE receiver is investigated with the application to the multi-code system. It i...

Wireless Mesh Network (WMNs) is a promising technology that has been accepted favorably by the Internet Service Providers (ISPs). ISPs use it to provide last mile broadband connectivity end users. This popularity arises from fact, inter operates well with diverse wireless systems and provides robust fault tolerance high degree of redundancy reliability. Routing metrics plays crucial part in per...

In Cognitive Radio Networks, the application throughput is not only affected by primary user activity but also by numerous environment factors such as interference. Therefore, channel assignment for cognitive radio networks should not only consider channel idle time but also an error rate perceived on the channel. The spectrum-aware channel assignment is vital to efficiently utilize the network...

We propose a downlink multiple-input multipleoutput (MIMO) multi-carrier code division multiple access (MCCDMA) system with adaptive beamforming algorithm for smart antennas. The algorithm used in this paper is based on the Least Mean Square (LMS), with pilot channel estimation (PCE) and the zero forcing equalizer (ZFE) in the receiver, requiring reference signal and no knowledge channel. MC-CD...
