<p>PURPOSE: A CDMA mobile station device is provided to enhance the accuracy of demodulation of a data signal when wirelessly receiving a control spread signal and a data spread signal from a device of a base station. CONSTITUTION: Non-orthogonal spread signal generating means(4-5) use a non-orthogonal spread code to generate a non-orthogonal spread signal whose phase rotation in a wireless transmission line is compensated, subtraction means(7,8) subtract the generated non-orthogonal spread signal from a received signal as an interference signal and data signal demodulation means(9,10) use the data signal use spread code to demodulate the data signal from the result of subtraction of the subtraction means. Furthermore, there are other configurations as a configuration to eliminate an entire notice signal, a configuration corresponding to a band limit and a configuration employing a suppression coefficient.</p> |
