Latest Patents

One of Iwakuni's latest patents is a diversity reception apparatus. This apparatus features a simple configuration that includes only one AD conversion unit and is designed to receive analog modulated signals. It incorporates a switching unit that analog-multiplexes signals received by two antennas using a time-division method, which is placed in front of the AD conversion unit. Additionally, it includes a time-division separation unit that obtains time-division multiplexed signals digitized at the same frequency as the AD conversion unit. This unit also separates the time-divided signals into individual signals per antenna. Furthermore, the apparatus has signal quality judgment units that assess the quality of each time-divided signal and a composition unit that performs composition processing based on the signal quality.

Another significant patent by Iwakuni involves a transmission method for digital broadcasting, along with a digital broadcasting receiver and a digital broadcasting station system. This innovation allows for the transmission of program data, which includes digital audio and video data, using terrestrial waves. The program data is multiplexed with download data and reference information, which correlates the download data with the program data. These multiplexed signals are then transmitted over a specific frequency band.
