Description: In this project an adaptive beamforming technique is proposed based on directly minimizing the BER1. A particular approach that has shown real promise in achieving substantial capacity enhancements is the use of adaptive antenna arrays. A beamformer appropriately combines the signals received by the different elements of an antenna array to form a single output. Classically, this has been achieved by minimizing the mean square error (MSE) between the desired output and the actual array output. It is demonstrated that minimum BER (MBER) approach utilizes the antenna array elements more intelligently than the standard MMSE2 approach, since it directly optimizes the system’s BER performance rather than minimizing the MSE, where the latter strategy often turns out to be deficient.

Consider the LMS algorithm applied to an adaptive minimum-variance distortionless response (MDVR) beamformer consists of a linear array of five uniformly spaced sensors. The spacing d between adjacent elements of the array equals one-half of the received wavelength . The beamformer operates in an environment that consists of two components: a target signal impinging on the array along a direction of interest and a single source of interference coming an
unknown direction. It is assumed that these two components originate independent sources and that the received signal includes additive white Gaussian noise at the output of each sensor. Platform: |
