On the Use of Signal-to-Noise Ratio Estimation for Establishing Hidden Markov Modelsrated. A dynamic channel model is first found by monitoring the receiver input signal-to-noise ratio (SNR). Each channel state is then embedded with a binary error Fritchman model From the Markov model, system performance parameters, such as the bit-error-rate (BER), can be determined directly.

Capacity of Channel Hopping Channel Stream on Cellular Digital Packet Data (CDPD)repeat-request protocols are used. For example, if the offered voice traffic at a 54-channel base station is 22 Erlangs, the data base station can achieve a throughput improvement of a factor of 2 and a coverage area increase of 47%
