Abstract

This paper compares the performance of soft handoff (SHO) between IS-95A and IS-95B/cdma2000 by using the following performance indicators : quality of traffic channel (E_b/N_o), outage probability, new call blocking probability (P_B), handoff call blocking probability (P_HO), expected number of base stations in active set (NO_BS), expected number of changes in active set (NO_update) and Trunking Resource Efficiency (TRE) with specific Poisson distributed call arrival and exponential distributed holding time process. By comparison of all parameters, IS-95B/cdma2000 SHOs tends to have a higher performance than IS-95A SHO. Moreover the SHO thresholds affect the triggering and the releasing of 2-way and 3-way SHOs with different distance of both algorithms
