    Abstract: A system and method for optimizing usage of a communications transmission medium. The transmission medium may be sliced into time and frequency domains so as to create time-frequency slices for assignment to users having varying access rates and user-application requirements. Through scheduling of the various speed users within the frequency and time domains, the system and method can efficiently allocate and make use of the available spectrum, thereby accommodating higher rate users requiring greater bandwidths and time slot assignments while still preserving cost-efficient access for lower speed users. Depending on the signal modulation scheme, the time-frequency slices may be allocated on non-contiguous frequency bands. The system and method is also applicable to code-division multiple access (CDMA) techniques by slicing the available code space along time-code domains, frequency-code domains or, in three dimensions, along time-frequency-code domains. Users may be efficiently scheduled based on code space requirements so as to optimize use of the communication medium.

    Abstract: A multi-code code division multiple access system allows a user at a radio transmitter unit to dynamically change its source data bit rate. In response to a user input selecting one of the plurality of source bit rates, an adjustable coding circuit in the transmitter spreads and transmits the user's digital bit stream received at the selected bit rate to a channel bit rate which at least equals the highest bit rate of the plurality of source bit rates. The plurality of source bit rates includes a basic bit rate R and at least one bit rate which is a multiple M of the basic bit rate R, where M is an integer of at least 1. The user's input selects a particular user source bit rate by identifying a basic bit rate multiple M to a base station that is to receive the transmission.

    Abstract: This invention is a technique for the substantially instantaneous self-healing of digital communications networks. Digital data streams from each of N nearby sources are combined and encoded to produce N+M coded data streams using a coding algorithm. The N+M coded data streams are then each transmitted over a separate long haul communications link to a decoder where any N of the N+M coded data streams can be decoded uniquely to produce the original N data streams. The orginal N data streams are then distributed to their respective separate end destinations. If any M or less of the N+M long haul communications links fails, i.e. as in a telephone line that gets cut or a long distance switch that fails, no rerouting of traffic need be done. Rather, the receiver detects loss of carrier on the failed link(s), and immediately supplies the missing data by decoding the data from the at least N remaining links. The technique overcomes a long felt problem of trying to reroute traffic by using sophisticated resource allocation techniques when a communications link fails.

    Abstract: In a multipoint data communication system using quadrature-amplitude modulation, a master modem and a plurality of tributary modems are interconnected via respective transmission channels. Adaptive equalizer circuitry in the master modem equalizes the channel from a particular tributary by multiplying samples of signals received from the tributary by an ensemble of tap coefficients associated with the tributary. The tap coefficient ensembles for each tributary are stored in a memory from which they are retrieved at the start of transmission from that tributary. Timing acquisition circuitry within the master modem adjusts the phase of the latter's sampling circuitry at the start of transmission from a given tributary so that the received signals are sampled at the correct time points. In particular, a timing acquisition signal is transmitted by the tributary. The master samples and equalizes the received timing acquisition signal to form a succession of timing acquisition equalizer outputs. Each timing acquisition equalizer output is multiplied by its complex conjugate to form a timing acquisition envelope sample. The time by which the operation of the sampling circuitry is to be advanced or retarded is determined as a trigonometric function of successive timing acquisition envelope samples.

    Abstract: The present invention provides a Diversity Coding—Orthogonal Frequency Division Multiplexing (DC-OFDM) system and method that applies diversity coding to OFDM-based systems and provides improved probability of successful reception at the receiver and transparent self-healing and fault-tolerance. Diversity coding is well suited for OFDM-based systems because of its spatial diversity nature (parallel links). DC-OFDM provides the best performance when the probability of link error is high or when a link (sub-channel) fails. Also, by implementing diversity coding in OFDM-based systems, a reliable communication can be provided that is quite tolerant of link failures, since data and protection lines are transmitted via multiple sub-channels.
