Abstract:
The hig h quality differential coding CDMA ( diffCDMA ) system w ith instantaneous phase that is new technolo gy in communication field has been dev ised. The principle of modulation w ith / 4-DQPSK instantaneous phase and the illustr atio n of demodulation has been devised. The new Walsh code taken as spr ead- spectrum code has been adopted. The application of the t wo items of important technolog y to the differential coding CDMA ( diffCDMA) system improves the capacity and eliminates t he fatal tr ansmission err or when communications are carried out from hig h speed r unning mobiles through such urban environment as rapid mult-i ray Rayleihg channel. This two items of techno logy inuoeve not only mathematical problems of communication theor y but also electronic cir cuit problems in diffCDMA system.
