Abstract:

In many adaptive array designs the adaptive algorithm is implemented digitally and the element weighting is quantized. The error incurred when quantizing element weights gives rise to a degradation in the dynamic range performance of an adaptive processor. This phenomenon was studied with an experimental adaptive array that implements the least mean square LMS algorithm. Quantization effects on the dynamic range of the adaptive processor were measured, and a theoretical relationship between quantization and dynamic range is formulated. Author
