With a total of 19 patents to his name, Moriyama has made strides in developing methods that enhance the efficiency and effectiveness of communication systems.

Latest Patents

Among his latest patents is a transmission control method and information processing apparatus. This invention provides a method for multiple transmitting stations connected to a wireless communication partner receiving station by non-orthogonal multiple access. Each station can transmit the same signal to the receiving station by repetition for a predetermined number of times at a predetermined cycle. The information processing apparatus acquires information indicating a code word length for each transmitting station and assigns transmitting power to ensure a required power difference between stations. The shorter the code word length, the higher the receiving power at the receiving station.

Another notable patent is a wireless communication control method that suppresses interference using an MMSE weight in environments where the number of transmission stations exceeds the number of reception antennas. The receiving station calculates the power of interference signals and adjusts the MMSE weight accordingly to optimize signal reception.
