dc.description.abstract Various methods and techniques have been introduced and applied to advance the state of the art of mobile wireless communications technology. For example, some techniques are applied to overcome the problem of multipath caused by the mobile environment. Multipath produces replicas of the wanted signal which arrive at the receiver with different time delays. If not dealt with properly, this environment will greatly deteriorate the quality of the wanted signal. The so-called multiuser feature of many wireless communication systems will also add some interference to the signal of interest. This thesis makes an attempt to improve the performance of wireless communication systems that use either pilot-based or blind equalization techniques to obtain channel side information. Specifically, these techniques are concerned with the estimation of multipath parameters in order to improve system performance. By inserting some pre-defined code which is called a pilot code on each pre-defined segment of a data block, we can recover the signal by pilot-based methods. Using an adaptive method, some knowledge of the channel characteristics and input source, we can achieve acceptable error rate using blind equalization as an alternate solution to pilot-based. Finally, new enhancements are added to blind equalization to improve its performance further. en
