Steered beam and LMS interference canceler comparison
Abstract
The performance of two kinds of interference cancelers is compared, namely, a constrained steered beam interference canceler (CSBIC) and a least mean square interference canceler (LMSIC). For simplicity, this is done for a two-element array. In the comparison the array output desired signal-to-interference power ratio (SIR) and the desired signal-to-noise ratio (SNR) are used. These power ratios are obtained for the CSBIC and LMSIC under two sets of conditions: (1) the error in the assumed angle of incidence for the CSBIC is small, and the LMSIC operates in a code-tracking mode; and (2) the error in the assumed angle of incidence for the CSBIC is large, and the LMSIC operates in a code-acquisition mode.
