Effects of components nonidealities upon the performance of adaptive antenna array processors

Abstract EN

This paper describes the effects of component nonidealities upon the performance of analog and sampled data adaptive antenna arrays.

It is shown that the effects of analog implementation differ significantly from those encountered in ideal cases.

It is also shown that the effects of nonzero mean errors, such as offset voltages and nonlinearities of the input multipliers contribute an excess mean square error which is inversely proportional to the parameter which controls the stability and the rate of convergence of the algorithm.

A configuration is presented which minimises these effects by distributing the loop gain of the first multiplier around the signal path.
