A novel adaptive beamforming algorithm for antenna array CDMA systems with strong interferers
Blind beamforming based on the maximum signal-to-noise ratio (MSNR) can improve the performance of the array system only when the processing gain of the given code-division multiple-access (CDMA) system is high enough such that the desired signal can become dominant after the despreading [3], [15]. In this paper, we consider a maximum signal-to-(interference plus noise) ratio (MSINR) beamformin...
متن کاملAdaptive Beamforming Algorithm for Antenna Array CDMA Systems in Multipath Fading Channels Using Modified Bussgang Algorithm
In this paper a blind algorithm for combining Rake receiver and beamformer is introduced. It is shown that a blind adaptive beamforming is possible by directly utilizing bussgang algorithm. But these algorithms may converge to local minima therefore some modification is applied for decreasing of the probability of convergence to local minima. It is demonstrated through the various computer simu...
متن کاملAdaptive Digital Beamforming Antenna Array for High Speed Communications
The rapidly increasing demand for PCS has provided the impetus to design adaptive antenna arrays to improve spectral efficiency and enhance system capacity. With increasing data rate in some PCS application like DECT( Digital European Cordless Telecommunications), higher BER would degrade the system performance further. An adaptive antenna array testbed using 12 elements was built to evaluate i...
متن کاملA novel adaptive beamforming algorithm for a smart antenna system in a CDMA mobile communication environment
An alternative way of adaptive beamforming is presented in this paper. The main contribution of the new technique is in its simplicity with a minimal loss of accuracy. Total computational load for computing a suboptimal weight vector from each new signal vector is about (2 2 + 5 ). It can further be reduced down to (3 ) by approximating the autocorrelation matrix with the instantaneous signal v...
متن کاملPerformance of Adaptive Beamforming with Multiport Parasitic Array Radiator Antenna
Modern wireless communications systems require improvement in capacity and data transmission speed. Adaptive array antennas separate spatially a desired wave from interference waves by controlling their radiation or beam pattern directivity. A digital beamforming (DBF) array performs adaptive beamforming by digital signal processing. However, the circuit scale, number of RF channels and power c...
