Latest Patents

Konno's latest patents include a communication device for transmitting data using multilevel coding. This device generates a modulated signal with 32 QAM, which involves a modulator, a first encoder, and a second encoder. The modulator maps each symbol in a data frame that includes transmission data, a first code, and a second code to a signal point among 32 QAM signal points. The first encoder encodes the data using a first coding scheme to generate the first code, while the second encoder encodes a bit string formed from one specified bit in five bits allocated to each symbol in the data frame to generate the second code. The mapping performed by the modulator ensures that each pair of adjacent signal points is different in terms of the specified bit.

Another significant patent by Konno is a device and method for transmitting data using multilevel coding, which also includes a communication system. This device generates a modulated signal with quadrature amplitude modulation. Similar to his previous patent, the modulator generates a modulated signal by mapping each symbol in a data frame that includes data, a first code, and a second code to a signal point among signal points of the quadrature amplitude modulation. The first and second encoders work in tandem to encode the data and generate the respective codes, ensuring that adjacent signal points differ in terms of the specified bit.
