Digital modular adaptive antenna and method

摘要

An adaptive antenna is implemented using a modular array element module. The array element module comprises an antenna element of the adaptive antenna. The antenna element has a weighting circuit which is coupled to a previous weighting circuit within a previous array element module in a concatenated manner. The weighting circuit is configured to apply a complex weight to antenna samples and to add the result to the output of the previous weighting circuit. The antenna element is also coupled to a cross-correlation measurement circuit configured to cross-correlate antenna samples with adaptation error samples to provide cross-correlation measurement samples to a controller which determines a weight applied by the weighting circuit.
