Title: Kenichi Murayama: Innovator in MIMO Systems
Introduction
Kenichi Murayama is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of telecommunications, particularly in the development of MIMO (Multiple Input Multiple Output) systems. His innovative work has led to the filing of multiple patents, showcasing his expertise and dedication to advancing technology.
Latest Patents
Kenichi Murayama holds 2 patents related to MIMO systems. His latest patents include a transmitter, receiver, and semiconductor chip designed to improve overall Bit Error Rate (BER) characteristics. The transmitter maps data distributed among transmit antennas onto an IQ plane to generate carrier symbols. It then applies inter-polarization interleave processing in a time direction to these carrier symbols, generating OFDM (Orthogonal Frequency Division Multiplexing) signals. The receiver demodulates the OFDM signals to produce complex baseband signals and applies a first deinterleave processing in a time direction to generate time deinterleaved data. Furthermore, the receiver performs MIMO separation processing on the time deinterleaved data to create multiple sets of MIMO separated data, followed by a second deinterleave processing between the receive antennas to generate carrier symbols.
