USER EQUIPMENT CDMA SYSTEM TRANSMISSION MATRIX COEFFICIENT CALCULATION

A UE(User Equipment) for performing CDMA(Code Division Multiple Access) system transmission matrix coefficient calculation is provided to synthesize convolutions of channel response, scrambling codes, and spread codes in order to configure system transmission coefficient matrices, as equally maintaining execution time and circuit size related to independently conducting each of convolution. A real number component shift register and an imaginary number component shift register have 2.sup.N positions, respectively. The first real number component adder circuits(A1-A4,A9-A11) are connected at 2.sup.N positions which are even-numbered with the register. The second real number component adder circuits are connected at 2.sup.N positions which are odd-numbered with the register. The second imaginary number component adder circuits are connected at 2.sup.N positions which are W even-numbered with the register. A control circuit(101) controls the registers and the adder circuits to be operable based on spreading factors of communication signals corresponding to a series of processed data values.
