Basically, the algorithm is based on adjusting the complex zeroes of a power inversion array in a time-multiplexed manner to track all the sources in the environment. To preserve the desired signal which is supposed to be closest to the look direction of 0°, the algorithm removes the zero with the shortest distance to ej0 so that the directional response consists of only nulls steered at the jammers. When compared with the least mean square (LMS) algorithm employing zeroth and first-order look direction constraints, the new algorithm has about the same implementation complexity, is considerably faster, and possesses a much better signal-to-noise ratio (SNR) performance when the look direction is erroneous. | Source Title: | IEEE Transactions on Aerospace and Electronic Systems | URI: | http://scholarbank.nus.edu.sg/handle/10635/81112 | ISSN: | 00189251 | DOI: | 10.1109/7.395237 |
