摘　　要：Cooperative communication networks have been studied and analyzed for many years for enhancing system performance,capacity,and reducing interference with the least focus on handover in cooperative communication scenarios.This paper focuses on trial field testing system for evaluating the proposed handover scheme called slide handover(HO).An automatic power allocation technique is coupled with slide HO scheme and its performance is also evaluated under cooperative networks.Our proposed scheme has achieved 100%successful HO executions in our field trial system.Block error rate(BLER)and slide HO are tested and analyzed in this trial system,and it is shown that the capacity of cooperative networks in these trials implementation has improved and maintained the expected quality of service.BLER below1%is noted at different testing locations which occasionally reached to 10%.Real-time video streaming performance is tested at different trial locations,and uniform streaming performance is noted at all different locations including during the HO process.This implies the improved HO delay of the proposed slide HO as compared to traditional HO techniques.Cooperative communication networks have been studied and analyzed for many years for enhancing system performance, capacity, and reducing interference with the least focus on handover in cooperative commu- nication scenarios. This paper focuses on trial field testing system for evaluating the proposed handover scheme called slide handover （HO）. An automatic power allocation technique is coupled with slide HO scheme and its per- formance is also evaluated under cooperative networks. Our proposed scheme has achieved 100 % successful HO executions in our field trial system. Block error rate （BLER） and slide HO are tested and analyzed in this trial system, and it is shown that the capacity of cooperative networks in these trials implementation has improved and maintained the expected quality of service. BLER below 1% is noted at different testing locations which occa- sionally reached to 10 %. Real-time video streaming per- formance is tested at different trial locations, and uniform streaming performance is noted at all different locations including during the HO process. This implies the improved HO delay of the proposed slide HO as compared to traditional HO techniques.
