The performance of a mobile handset with a top-mounted monopole and back-mounted internal monopole was determined in the field. Handset field tests were conducted both for the handset attached to a phantom-head model and held by a human operator so that the effect of hand blockage and coupling were measured. The measurements were made on the IS-95 (CDMA) SPRINT PCS system in various parts of San Diego. Logged data was analyzed for single antenna performance, selection diversity combining, maximum ratio combining, and optimum combining.","abstract_html":"In this thesis cellular handset and mobile terminal forward link sensitivity improvements due to dual-antenna systems with smart-antenna combining algorithms were determined.
