CONSTITUTION:A specified complex number system signal with length (n) is applied to an input terminal 1. This signal is branched into 4 with a branch means 2 and they are applied to multiplication means 31-34 respectively. Signals multiplied with the N-order orthogonal matrix components with the means 31-34 are applied to correlation filters 41-44 respectively. As a correlation filter, a matching filter introducing the autocorrelation signal for the applied signal is used. The four autocorrelation function signals ouputted from the filters 41-44 are summed at an adder 5 and a pulse-like signal with a narrow time width can be outputted from an output terminal 6.,下面是Filter circuit专利的具体信息内容。
