Latest Patents
One of his latest patents involves a software portable telephone. This invention describes a process where a received signal, inputted from an antenna, is processed through a received signal mixer and an A/D converter to a demodulator. The demodulator operates according to software downloaded from a program memory into a software memory. The output digital signal from the demodulator is then processed by a base-band signal processor and transmitted through a man-machine interface. On the transmission side, the signal to be transmitted is inputted to a modulator, which follows a route opposite to that of the received signal. The modulator output is converted to an analog signal via a D/A converter and then mixed to a carrier frequency before being transmitted through the antenna.
Another notable patent is related to a radio set and frequency converting method. This invention aims to create a radio set in a direct conversion system, minimizing any undesired influence of a transmission system on the reception system. The frequency conversion circuit expresses the local signal frequency used in the process, ensuring that no interference wave is generated for the received signal.
