A circuit that had been earlier lab-tested to eliminate multi-antenna interference in the In-mine (IM) system was fabricated, implemented and tested successfully in a system setting. An adaptive, tracking comb-filter for the through-the-earth (TTE) communications system was designed and implemented. This resulted in noticeable noise reduction. Studies for multi-channel transmission have begun
