Latest Patents
Ooya's latest patents include a communication system, transmitting device, receiving device, and communication method. These innovations aim to achieve high usage efficiency of frequencies without requiring cooperation from multiplexed users. The communication system operates over frequency channels that are established by dividing a frequency bandwidth assigned to the system. It allows for interference between channels by overlapping adjacent frequency channels in the frequency domain. Additionally, the transmitting and receiving device transmits and receives signals while minimizing interference between symbols at a waveform level for each channel, thereby reducing the occupied bandwidth. The receiving device is equipped with an Inter-Channel Interference (ICI) removal and Inter-Symbol Interference (ISI) compensation filter, which serves to either remove interference between channels or compensate for interference between symbols.
