Multipath fading reduction using a phase-conjugating array in a dual-reflector environment

This paper investigates the use of a phase-conjugating array to mitigate multipath fading in wireless communications. A four-element phase- conjugating array is placed in a multipath environment consisting of two reflectors parallel to the primary signal path. The distance between the interrogator and receiver is varied to produce multipath signals of varying angles of incidence. A comparison between the phase-conjugating array and a conventional four- element array shows that the phase-conjugating array reduces fading by up to 14 dB, showing that the phase- conjugating array is a viable solution for multipath mitigation.
