  • Method to determine transmission quality
    Patent number: 5214687
    Abstract: A method determines the transmission quality of a signal transmitted by a base station and received by a mobile station in a cellular digital radio telephone network. The mobile station determines the phase error of detected bits a the input of the channel decoder, calculates the average and variance of the phase error. The average and variance are used to calculate the S/N ratio. The S/N ratio information is transmitted to a base station which converts the S/N ratio to a value defining the BER estimate of the received signal.
