Abstract: A synthesis signal which was reproduced from a reproducing apparatus and converted into an analog signal includes an analog information signal and a copy control code. The copy control code is modulated by a spread spectrum. A code reading unit of the recording apparatus extracts a copy control code by an inverse spread spectrum. A code changing unit changes the copy control code by a spread spectrum as necessary. An output signal of the code changing unit is converted into a digital signal. The digital signal is subjected to processes necessary for recording and is recorded to a recording medium.

Abstract: It is possible to cope with a change of the transmitting capacity in wireless communication such as wireless telephone system. A plurality of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.

Abstract: A selector that selects an orthogonally detected output signal of I channel and an orthogonally detected output signal of Q channel and that outputs the selected signals to a path for obtaining a demodulated output signal of I channel is provided. In addition, a selector that selects an orthogonally detected output signal of Q channel and an orthogonally detected output signal of I channel and that outputs the selected signals to a path for obtaining a demodulated output signal of Q channel is provided. These selectors are switched corresponding to whether or not a PN code of I channel is the same as a PN code of Q channel. An output signal of the selector of the path for obtaining the demodulated output signal of I channel and the PN code of Q channel PNQ are ex-ORed and output as a de-spread output signal of I channel. An output signal of the selector of the path for obtaining the demodulated output signal of Q channel and the PN code PNI of I channel are ex-ORed and output as a de-spread output signal of Q channel.
