Abstract

This paper addresses the problem of equalizing a (narrow-band) multipath channel using data from an array of sensors. By exploiting the structure inherent in the data, it is shown that the number of multipath rays that can be uniquely identified is on the order of the number of data samples collected, rather than the number of sensors as in most direction finding applications. Two equalization algorithms are presented, both based on a frequency domain representation of the data and the availability of array calibration data. The performance of these algorithms is compared with that of several other recently developed equalization techniques, and is shown to be superior provided the calibration data is reasonably accurate
