Abstract: One aspect of the present invention is a method for the wireless transmission of information from one or more antennas to one or more separate users. The method comprises processing information to produce transmission vectors that minimize simultaneous interference between separate user channels and adjusting the radiation patterns to minimize total system radiation power for users specified capacities. In another aspect, the present invention includes apparatus and methods for providing multiple users of a network with information in such a manner that only the user that the signals are intended for receives the information.

Abstract: A method for the direct estimation of configuration parameters defining the make-up of a physical system, such as cable lengths and gauges in the case of telephone subscriber loops, from boundary or end-point measurements of the physical structure, such as the impedance or return loss response of a subscriber loop, due to a probing source.

Abstract: Techniques whereby a transmitter/receiver pair are cooperatively arranged to buffer incoming data to both the transmitter and the receiver. The transmitter and receiver of the pair are coupled, generically, by pre-existing channel which has a known, fixed capacity. The transmitter/receiver pair exploits whatever delay is permissible, as determined by end-users of the data, for the data stream or streams that are using the channel for the purpose of accommodating periods of excessive instantaneous aggregate data transfer demands. The matched transmitter/receiver pair thereby permits (i) the transmission of a variable rate stream over a channel with capacity less than the peak rate of the stream, or (ii) the multiplexing of variable and/or fixed rate data streams.

Abstract: A method and system use voiceband transmission characteristics to estimate the viability of deploying broadband services over a subscriber loop in the public switched telephone network. The system gives network service providers the ability to predict the performance of broadband transmission channels, such as ADSL, on a subscriber loop from a central location and without reliance on outdated loop records maintained by a carrier. Based on this predicted performance a network service provider is able to efficiently determine the viability of deploying ADSL to a subscriber and, in turn, determine the viability of deploying ADSL in entire areas by creating an ADSL--ready consumer-lead list. The method comprises establishing an end to end voiceband modem connection from a logic device to a remote computer over a facility wherein the only analog elements reside in the subscriber loop.

Abstract: A transceiving methodology and concomitant transceiving system wherein high speed, bursty channels are combined with uniform data rate services into a single, interleaved data stream. A system for communicating both a uniform data stream and a bursty data stream over a communication medium includes: (i) a transmitter for combining the uniform data stream and the bursty data stream into a single, interleaved stream, and for propagating the interleaved stream over the medium; and (ii) a receiver for processing the single interleaved stream to separate the uniform data stream and the bursty data stream.
