Abstract:
1. A method of identifying the transmission channel condition of a signal received by a receiver of a mobile device, the method including the steps of: receiving said signal from a transmitter of a communication network provider, wherein said transmitter is in a known location, and wherein said signal includes signal information which is provided with said signal by said communication network provider; identifying, via said mobile device, arrival information of said signal; determining, via a processor of said mobile device, signal location information from at least one of said signal information and said arrival information; estimating an entropy of a channel impulse response of said signal; and determining a channel condition from the estimated entropy, wherein possible channel conditions for the channel condition are said signal including components that have traversed a direct path and non-direct paths, and said signal including components that have traversed non-direct paths only.
