Channel parameter estimation in Rayleigh fading channel

Electronics and Communications in Japan (Part III: Fundamental Electronic Science), 2005
In wireless communication environments such as indoors and in a relatively narrow region for which applications have recently started, the information transmission speed is sufficiently faster than the fading variation. In such cases, the fading variation can be viewed as a colored probability process with autocorrelation.

Adaptive channel estimation for high Doppler channel

2015 3rd International Conference on Signal Processing, Communication and Networking (ICSCN), 2015
This paper considered about how the channel estimation effectively done for high-speed mobility system. Here the transmission rate greatly varied depending on speed of the mobile moving far away or close to the base station. The impulse swings are frequency shifts and delay spread various for each symbol called multipath fading is because of this OFDM ...

HF channel parameters estimation

First IEEE Signal Processing Workshop on Signal Processing Advances in Wireless Communications, 2002
A new approach in HF channels parameters estimation is presented. It permits the improvement of the link quality analysis procedures involved in the link establishment techniques. This is achieved thanks to the estimation of the parameters that completely define the most widely used HF channel model: the Watterson (1970) model. The estimation method is

Blind GSM channel estimation

1997 IEEE 47th Vehicular Technology Conference. Technology in Motion, 2002
The bandwidth efficiency of many communication systems could be improved if the transmission channel was estimated blindly, i.e. without resort to training sequences. As an example, we investigate in this paper the applicability of two algorithms for the blind identification of mixed-phase linear time-invariant FIR systems to the estimation of mobile ...

Modified UWB channel estimation

2005 2nd Asia Pacific Conference on Mobile Technology, Applications and Systems, 2005
Ultra wideband (UWB) wireless communication is a new type of radio communication. One of the main applications of UWB in the future focuses on wireless personal area networks (WPAN). Channel estimation is very important for OFDM based UWB system because of its coherent demodulation.

ADAPTIVE CHANNEL ESTIMATION FOR MAXIMUM LIKELIHOOD SEQUENCE ESTIMATION

IFAC Proceedings Volumes, 1992
Abstract The paper reviews the problem of adaptive channel estimation for maximum likelihood sequence estimation. It explains necessity of channel estimation for operation of the ML receiver, reviews a few of the most important receiver structures, discusses several adaptation algorithms and joint blind adaptive sequence and channel estimation.
