Based on the analysis of CDMA handoff, an improved two threshold soft handoff scheme is proposed and analyzed in detail theoretically. Combining with the minimum dwelling time method, we propose a hybrid handoff scheme and compare its performance with that of conventional guard channel scheme and minimum dwelling time scheme, respectively. Results show that the suggested scheme is of good performance. Based on the analysis of CDMA handoff, an improved two threshold soft handoff scheme is proposed and analyzed in detail theoretically.
