performance analysis of cdma 1x ev-do revision a enhanced access channel
In this paper, we analyze the throughput and delay for the messages sent on Enhanced Access Channel (EACH) in High Rate Packet Data (HRPD) revision A through extensive simulations. We also provide an analytical model and the corresponding throughput equations to validate the simulation results. The analysis predicts that the capacity is directly tied to the ratio between the access channel cycle size and the message (capsule) length. The smaller this ratio, the larger is the normalized throughput. We present results that help in sizing the number of resources for an expected EACH load. We also study the impact of different EACH parameters on the throughput and delay.
