CMA an Optimum Beamformer for a Smart Antenna System
In this paper constant modulus algorithm (CMA) and least mean square (LMS), kind of blind and nonblind algorithms used for adaptive beamforming are presented. These algorithms are embedded in smart antenna which calculates optimum weight vector that minimizes the total received power except the power coming from desired direction. The efficiency of CMA and LMS algorithms is compared on the basi...
متن کاملA fast neural beamformer for antenna arrays
A fast neuro-beamformer is presented in this paper. The new algorithm is based on the radial-basis function network. To meet real-time requirement, we customize the basis function for fast computation, and apply recursive least square learning rule to speed up the network training. By comparing the effects of center location and distribution, we can achieve a minimum network for recalling. The ...
متن کاملSmart antenna for wi-max radio system
In simple words, smart antenna is such that it can sense its environment and can adjust its gain in different directions accordingly. They provide a smart solution to the problem of communication traffic overload i.e. they increase the traffic capacity. They also improve the QOS. RF spectrum is a limited resource and is becoming crowded day by day due to the advent of new technologies. The sour...
متن کاملConstrained Beamformer Optimization for Adaptive Antenna Arrays
Digital beamforming algorithms are commonly used for spatial filtering which effectively result in more benign channel characterestics with reduced interference and delay spread. A new constrained beamforming (CBF) algorithm is presented which allows optimum beam steering and interference cancellation for arbitrarily spaced directions The proposed CBF combines the properties of the Bartlett and...
متن کاملAdvances in smart antenna system
This paper presents brief account on smart antenna (SA) system. Smart or adaptive antenna arrays consist of an array of antenna elements with signal processing capability that optimizes the radiation and reception of a desired signal dynamically. SAs can place nulls in the direction of interferers via adaptive updating of weights linked to each antenna element. SAs thus cancel out most of the c...
