Abstract
Body wearable antenna systems designed for Land Warrior/Ground Soldiers are vulnerable to signal cancellations due to multipath and higher losses . Diversity and MIMO techniques integrated with these antennas can mitigate multipath and shadowing effects to increase the overall link system gain. Under this effort, we propose several methods (switching among antennas with better reception, combining antenna with complex weights, beam shaping and beam steering, and polarization diversity) to implement diversity with novel signal processing techniques, and thus reduce signal to noise ratios to increase reception reliability for the Army’s tactical radio systems. Applied EM and its team members propose a comprehensive study to improve body wearable antennas . Techniques that mitigate multipath effects and interference are proposed. Concurrently, we will carry out experimental studies to verify the effectiveness of the proposed methods.
