摘要： The present invention provides a novel Geometric Harmonic Modulation (GHM) system. The GHM system operates in two modes, a preamble mode and a traffic mode. During the preamble mode, n+1 frequencies are each offset by a predetermined phase offset in a transmit unit and passed through a channel to a receive unit. The set of phase offsets is used as the spreading code in the transmit unit, and also acts as an `address` of receive units to transmit to. The receive unit monitors preamble signals to determine the phase offsets. When it recognizes a set of phase offsets, or `address`, which pertains to itself, the receive unit stores the phase offsets and uses these phase offsets to despread and decode the appended message. After the preamble mode is finished, the transmit unit enters the traffic mode and requests the message to be transmitted from the message source. A traffic carrier waveform is created by multiplying tones, each having its specific phase offset. Both analog or binary message are provided by a switching device in interleaved fashion to an appropriate modulator which encode the messages in the traffic carrier waveform. The receive unit detects a preamble carrier and recovers the particular preamble phase offsets to be used as the despreading `key`. The receive unit then senses then separates the binary from analog message signals and employs the phase offsets in despreading the received signal to recover the transmitted analog and binary messages in an interleaved fashion.

摘要： A highly fault tolerant method of radio communication of information in the form of a message packet employs a distributed network of transmitter/receivers `transceivers` each having a unique identification ("ID") number. An initiating transceiver creates a message packet having the ID of a transceiver intended to receive the message packet. It then broadcasts the message packet to transceivers within its transmission range. Each transceiver which receives the message packet checks to see if there are errors and sends an acknowledgement if no errors. The transceivers determine valid message packets by determining if the message has not expired, if it has not been seen before and there were no errors in the received message packet. The transceiver also determines if the transceiver ID in the message packet match its own transceiver ID, and if it does, is the message has been successfully transmitted to its intended transceiver. If the message packet is valid and the transceiver IDs do not match, the transceiver broadcasts the message to other local transceivers until a predetermined number of acknowledgements are received, or until the message expires. The transceivers which receive the message packet repeat the process.

摘要： A method, apparatus and system are provided for recognizing broadcast segments, such as commercials, in real time by continuous pattern recognition without resorting to cues or codes in the broadcast signal. Each broadcast frame is parametized to yield a digital word and a signature is constructed for segments to be recognized by selecting, in accordance with a set of predefined rules, a number of words from among random locations throughout the segment and storing them along with offset information indicating their relative locations. As a broadcast signal is monitored, it is parametized in the same way and the library of signatures is compared against each digital word and words offset therefrom by the stored offset amounts. A data reduction technique minimizes the number of comparisons required while still maintaining a large database.

摘要： A traffic carrier waveform W.sub.n (.PHI.,R;t) being the product of a number of tones is employed in transmitting blocks of information from a transmit unit to a receive unit. The tones are geometrically increasing multiples of a frequency of a fundamental tone. Each tone incorporates a tone phase. The selection of these tone phases uniquely identifies each transmitted signal. The tone phases also is used as a `key` in converting a message signal into a direct wide spectrum signal for communication. To insure that third parties do not decode the transmitted message, the tone phases are transformed to seed phases by a method known to both the transmit and receive units, but not to third parties. The seed phases are then transmitted by intermittent preamble carrier waveform to the receive unit which transforms these into the tone phases and decodes the message signal. The seed phases may be dynamically changed according to a sequence known or generated by both the transmit unit and receive unit. In another embodiment, the tone phases may also be prestored in both the transmit and receive unit, and there is no need to calculate and transmit seed phases.
