    • An existing TDRSS satellite communication system is incorporated, together with low-power ground-based remote transceivers of special design, and additional beamforming and steering elements at the ground terminals, to make possible digital communication between low power field transceivers and satellite ground terminals. The satellite communication system transmits to its ground terminals a composite signal, comprising amplified, phase-coherent signals received by an array of broad-coverage antennas on the satellite. The field transceiver transmits a pseudonoise coded signal spread across all or a portion of the satellite's receive bandwidth. At the ground terminals, the downlinked composite signal is processed by a beamformer to define a narrow, high-gain beam between the satellite and low-power transceiver. Signal processing gain and beamformer gain in combination serve to elevate the received, demodulated signals well above the noise level at the receiver. Through this invention, a large multiplicity of non-interfering reverse-link (remote-to-central) communication channels may be supported by a host satellite communication system of the nature described. By the introduction of forward link signal channels into the satellite ground terminal, and scheduling of forward link transmissions to the set of low-power remote transceivers along with normal transmit activities, highly useful two-way communication can be extended to a class of users not initially served by the satellite communication system.

    • A communications system operating in one or more frequency bands of various number of channels per band (for a total of N channels), and a novel transceiver for receiving these multiple bands of signals. The transceiver comprises an antenna and RF front end for each said band, a separate RF to IF downconverter for each said band. The IF for each band is centered at a succession of frequencies Fo such that the spectra for each band are non-overlapping, with the center frequencies. Analog-to-digital converter sampling rate is chosen such that one band is centered at baseband, and one or more other bands are centered at a specific relationship with the sampling rate such that each band is individually downconverted to baseband by appropriate selection of tap weight multiplying sequences (such as alternating +/− sequence for the case of Fo equal to one-fourth the sampling rate). An analog-to-digital converter converts analog signals to digital signals from the combiner. A digital downconverter converts the digital signals to baseband signals and a single digital processor sequentially time shared among all the bands and channels.

    • Most cable television systems in the United States (over 75% as of this application) are structured for one-way only service between the cable headend and the user. With more and more services being introduced that require a two-way connection with the user (e.g. impulse-pay-per-view, home shopping, Internet access), it has become necessary for more and more cable systems to upgrade to a two-way capability at considerable cost and over a fairly long period of time. The typical short-term solution to the lack of two-way capability is to send request backlinks over he user's telephone line. The problem with this solution is that when used, it ties up the telephone line and requires an additional telephone connection to be located near the cable set-top-box or modem. A more practical solution is the hub centered backhaul invention described herein. With this invention, users can operate their cable systems as if they were two-way systems, with all available interactive capabilities available. The request channel, however, will be intercepted at a central location between multiple users, and returned to the cable headend via an alternate communication path. The backlink request will be intercepted at a location in the cable distribution prior to hardware that precludes two-way transmissions, such as amplifiers.
    • 美国大多数有线电视系统(超过75%的应用程序)都是针对有线头端和用户之间的单向服务进行结构化的。 随着越来越多的服务被引入,需要与用户的双向连接(例如,按次付费浏览,家庭购物,互联网接入),越来越多的有线系统已经变得需要升级到双向连接, 相当的成本和相当长的一段时间内的方式能力。 缺乏双向能力的典型的短期解决方案是在用户的电话线上发送请求反向链接。 这个解决方案的问题是,当使用时,它绑定电话线,并需要额外的电话连接位于电缆机顶盒或调制解调器附近。 更实际的解决方案是本文描述的以枢纽为中心的回程发明。 通过本发明,用户可以像他们的双向系统一样操作其有线系统,具有可用的所有可用交互功能。 然而,请求信道将在多个用户之间的中心位置被拦截,并且经由备用通信路径返回到电缆头端。 在排除诸如放大器之类的双向传输的硬件之前,反向链接请求将在电缆分发的位置被拦截。
