Channel estimation using continuous particle swarm optimization

In broad spectrum a channel refers as a transmission medium through which information is transmitted. In channel, when the signal is transmitted there is an accumulation of noise at the received signal. To eliminate this noise from the channel different estimation techniques are used such as training sequences-based estimation, blind channel estimation. These techniques have some drawbacks such as implementation, convergence and efficiency problems. To conquer the problems in existing channel estimation techniques, we use continuous particle swarm optimization soft version algorithm (CPSO) which is used to optimize the solution by improving the candidate solution with respect to some quality measure.
