DF Directed Multipath Equalization

Thas paper addresses the problem of equalizing a (narrowband) multipath channel using data f r o m a n array of sensors. By exploiting the structure inherent i n the data, i t i s shown that the number o f multipath rays that can he uniquely identified is o n the order of the numher of data samples collected, rather than the number of sensor.s as in most direction finding npplicalions. Two equalization algorithms are presented. both based on a frequency domazn rcpresentation of the datn and the availahilzty of array cdibratzon data. The peTf0TmanCe of tliese algorithms zs compared with that o f several other recently developed equalazataon, techniques, and a s shown to he superaor proiizdrd the cnlzhration dnta z.9 rra.sonahly accurate
