Applying the Convex Metric and the Spatial Channel Model for HRPD Rev-A

[reza1217]

Computer simulations are often used to predict the performance of cellular networks. Typically, link level simulations are used to model the link between the access network (AN) and the access terminal (AT), while system level simulations are used to model a system consisting of many ANs and ATs. Since completely modeling the link between each AN and AT is impractical within system level simulators, link-to-system mapping techniques are used to incorporate link level behavior into system level simulators. The Equivalent SNR Method Based on Convex Metric (ECM) is one link-to-system mapping technique, which has been shown to produce accurate results for many different cellular systems. In this paper, we further examine the ECM by showing its performance for the Forward Traffic Channel (F-TCH) defined in the cdma2000 High Rate Packet Data (HRPD) Air Interface Specification. In particular, we show that the ECM produces consistent results for the F-TCH using the unique characteristics of the spatial channel model (SCM). We further show that the ECM is valid for simulating the HRPD early termination algorithm, a type of incremental redundancy.
