Abstract: A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.

Abstract: A multi-point communications system is set forth herein. The communications system comprises a head end unit disposed at a primary site and a plurality of receivers disposed at remote sites. The head end unit includes a transmitter for transmitting OFDM/DMT symbols over a predetermined number of bins across a transmission medium. The OFDM/DMT symbols are transmitted in periodically occurring formatted symbol frames. The cyclic prefix includes a predetermined periodic signal superimposed thereon. The receivers receive the OFDM/DMT symbols over a subset of the predetermined number of bins from the transmission medium and use the superimposed signals to attain symbol alignment. As such, the receivers are designed to process substantially fewer bins than the entire number of bins transmitted by the head end unit.

Abstract: A ship based cellular and satellite transceiver receives, demodulates and processes data, voice and video signals from a satellite transmitter and provides the processed signals in cascade to a OFDM and to a CDMA modulator and transmitter for transmission to a ship based mobile unit. The OFDM signal is transmitted in a Wi-Fi network and the CDMA signal is transmitted in frequency bands used by cellular phones and cellular connected devices. The ship based transceiver receives from a mobile unit, e.g. from a cellular phone or a computer an OFDM or a CDMA signal generated and transmitted by the mobile unit and receives, demodulates and processes the cellular phone transmitted signal and provides these processed signals for cascade processing, modulation and transmission to a satellite.
