Method for estimating connection quality, diversity combination method, and receiver |
摘要 |
The invention relates to a method for estimating the quality of a connection and a diversity combination method in a digital radio system in which the signals transmitted are in burst form, the bursts comprising a training sequence; and to a receiver comprising a filter matched to the received signal. To effect simple estimation of the quality of the connection, the receiver comprises means for forming a result vector of at most the length of the training sequence from the symbols of the output signal of the matched filter and the corresponding symbols of the training sequence; means for computing a mean value and variance for the symbols of the result vector; and means for forming a quantity proportional to signal quality as a quotient of the squared mean value of the result vector and the variance of the result vector.
