METHOD OF DETECTING THE CHANNEL IDENTITY OF A NUMBER OF CHANNELS IN A MOBILE RADIO SYSTEM |
摘要 |
A method of detecting the identity of a radio channel and to ascertain whether the channel is a control channel or a traffic channel, in conjunction with convolution decoding in a mobile radio receiver. Channel identification is effected without such complete decoding. Part of a data block is decoded in accordance with the Viterbi algorithm as though the block represented a control channel. If the metric obtained after a given number of nodes is smaller than a given number of threshold values, the channel is considered to be a control channel and is thereafter decoded as such a channel. If the metric is greater than the threshold value, the channel is decoded as a speech channel.
