摘要： A method and apparatus for increasing the capacity of present and future satellite communication systems transmits signals from correspondent pairs of earth stations simultaneously in channels that have at least a partial overlap in bandwidth. Each receiver at each earth station subtracts from the received composite signal the portion of the composite signal which was transmitted by the receiving earth station. This leaves a desired signal which corresponds to the signal transmitted by the other earth station of the correspondent pair and which is then demodulated. Each receiver at each earth station thus reconstructs an estimated target signal which has the amplitude, delay, frequency and phase of the signal as transmitted from the earth station and retransmitted by the satellite. The reconstructed target signal provides a very precise estimate of the portion of the composite signal transmitted by the earth station. The reconstructed target signal estimate is provided by repeated correlations of known signals against signals which are only partially known in order to produce an output which can be filtered to eliminate further parameters. The further parameters are put back into the estimation process, and said portion of the composite signal is regenerated in this manner of iteration.
摘要翻译： 用于增加当前和未来卫星通信系统的容量的方法和装置在具有至少部分带宽重叠的信道中同时从对应的地球站对传输信号。 每个地球站的每个接收机从接收到的复合信号中减去由接收地球站发射的复合信号的部分。 这留下了对应于通信对的其他地球站发送的信号并且然后被解调的期望信号。 每个地球站的每个接收机因此重建估计的目标信号，该估计目标信号具有从地球站发射并由卫星重发的信号的幅度，延迟，频率和相位。 重建的目标信号提供了由地球站发送的复合信号的部分的非常精确的估计。 重建的目标信号估计是通过已知信号与仅仅部分已知的信号的重复相关来提供的，以产生可被滤波以消除其它参数的输出。 进一步的参数被放回到估计过程中，并且复合信号的所述部分以这种迭代的方式再生。

摘要： The present invention allows a modem to operate in both the voice band, from 300 to 3400 Hz, and also in the ADSL band, which extends above 3400 Hz. Unlike conventional ADSL modems, the present invention avoids the computationally-intensive operations required to extract all the available band of a telephone subscriber loop. Consequently, the present invention can be implemented with low-cost modifications to existing voice band modems. The present invention thereby offers higher data transfer rates at a fraction of the cost of more complicated ADSL modems. The present invention also provides bypassing functions, which allow communications through a modem located at the telephone central office side of a subscriber loop to be switched through a packet-switched network, which is capable of accommodating high data transfer rates, instead of a central office switching system, which generally imposes unnecessary limitations on data transfer rates.

摘要： DLL devices are built with multiple MAC address instead of a single MAC address, and provide a multiple virtual DLL interfaces to the upper layers (3-7) in a computer. This results in a new class of multi-function computers for attachment to a network system which take advantage of the multiple virtual DLL interfaces, to increase performance of the respective functions executed by the computer. Thus, a new network interface control apparatus and a new class of multi-function computer systems for attachments to networks are provided. The memory in the medium access control device stores a plurality of additional network addresses in addition to the assigned network addresses. The address filtering logic includes circuits responsive to the additional network addresses, such as logic for blocking a particular frame on at least one of the plurality of data channels when the source and destination address of a particular frame are found in the additional addresses stored in the memory. The plurality of data channels served by the media access control device may reside on a single physical interface, or in independent physical interfaces as suits the needs of a particular design. A high performance design would include independent buffering and queuing structures for each of the data channels. An alternative design may include shared buffering and queuing structures for a plurality of functional modules in the connected computer which have independent side network addresses.

摘要： The present invention allows telephone subscriber loops carrying data traffic between computer systems to be switched to an alternative connection through a data network, thereby unloading data traffic from the telephone network. The invention operates by means of a break switch, which selectively switches a plurality of subscriber loops between a central office switching system and a data network. The break switch is coupled to a concentrator which takes a plurality of inputs from the break switch and connects them to a smaller number of modems in a modem pool. The concentrator allows a subscriber line to connect to different types of modems within the modem pool, depending upon requirements of a particular subscriber line user. The modem pool connects through a network interface to a packet-switched network, such as the Internet. A number of different methods can be used to transmit a command to switch a subscriber loop from the central office switching system to the packet-switched network. A loop current detector, which is coupled between the plurality of subscriber loops and the break switch, can monitor on/off hook status of the subscriber loop in order to determine whether to switch the connection to the data network. Alternatively, the command to perform the switching can originate from a remote host which transmits the command through the data network to the break switch.
