Patent
Method and apparatus for receiving diversity signals for use in OFDM radio communication system
Kazumi Sato,Minoru Namekata +1 more
TL;DR: In this paper, the OFDM received signal frequency spectra distortions are compensated by using corresponding channel frequency responses, which are calculated by using a reference frequency spectrum generated in a reference spectrum generator.
Patent
Wireless transmitting device and wireless receiving device
TL;DR: In this article, a wireless transmitting device includes a first and a second antenna, a data and a long preamble sequence to estimate a channel response to the first and the second transmitters, and a controller to power on the transmitters at different timings, respectively.
Patent
Method of notifying function identification information and communication system
TL;DR: In this paper, the authors disclosed a notification method in a communication system of notifying specific multifunctionality information between terminal stations, where an expansion code is generated from both a user input code and a function identification code corresponding to a specific function.
Patent
Ofdm signal transmission method and ofdm signal transmitter thereof
TL;DR: In this paper, the authors proposed a scrambling scheme to improve transmission average power by controlling the amplitude of an orthogonal frequency division multiple (OFDM) time waveform and to improve the throughput by reducing transmission errors.
Patent
Retransmission control method and apparatus for use in OFDM radio communication system
TL;DR: In this article, a retransmission control apparatus for use in a radio communication system that uses an orthogonal frequency division multiplexing technique is presented. But it is not shown how the retransmissions can improve the average power of the transmitting signal.
