Title: Digital signal transmission device
Inventor: AKIYAMA TOSHIYUKI
IPC: H04L27/20
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a digital signal transmission device which is capable of suppressing the increase in the circuit scale of a digital orthogonal modulation/ demodulation part and also can satisfactorily deal with even a high transmission rate. SOLUTION: A filter which limits the bandwidths of signals I and Q to be inputted to an orthogonal modulation circuit 22' consists of the non-recursive digital 21'i and LPF 21'q having an odd number (2N+1) of taps. Then odd numbered (N+1) pieces of coefficients included in the tap coefficients are used for the LPF 21'i of the signal I, and even numbered N pieces of coefficient are used for the LPF 21'q of the signal Q, respectively. Then two types of signal value which are multiplied by two types of coefficient value symmetrical and equal to each other are added together, and then these coefficient value are multiplied by each other. As a result, the number of multiplication circuits necessary for a digital LPF can be reduced significantly and accordingly the circuit scale can also be reduced significantly.
