摘要： A communication system includes communication protocols that allow a single network or multiple neighboring networks to increase resource sharing and reduce mutual interference and increase their overall throughput. Various protocols apply to homogenous networks in which all power line communication (PLC) devices of multiple networks are interoperable with respect to full power line communication in a common PHY (specifications, signaling capabilities, modulation scheme, coding scheme, bandwidth, etc.) and to heterogeneous networks in which devices of some PLC networks are not interoperable with PLC devices of other PLC networks with respect to full power line communication given that the devices of the different networks do not employ a common PHY. With respect to heterogeneous networks, a protocol is provided to enable coexistence via a signaling scheme common to all of the devices of the network that allows resource sharing between the devices of the multiple heterogeneous networks. Homogeneous networks are those in which all nodes can communicate with each other using a common PHY, so that information about one PLC network can be transferred to another PLC network. Heterogeneous networks are those in which not all PLC networks can exchange information using their own native PHY, such as where users in different apartments or houses use different devices having different specifications, different signaling capabilities, modulation scheme, coding scheme, bandwidth and the like.

摘要： Crosstalk between subscriber loops used to transmit different broadband services through the same bundled telephone cable is a significant limitation to providing digital subscriber line services. A method for estimating the crosstalk, identifying the sources of the crosstalk and predicting additional sources of crosstalk are disclosed. The crosstalk sources are identified in the frequency domain by maximizing the correlation with a “basis set” of received crosstalk PSDs which consist of the cascade of a finite set of known transmit PSDs types times a representative set of crosstalk couplings. Multiple crosstalk types are identified with a technique of successive spectral subtraction. Once a type is identified the crosstalk disturber is compared against all other members of the complete set for that type. Additionally, Multiple Regression (MR) techniques and a Matching Pursuit (MP) algorithm are used to increase the ability of the system and method to identify various crosstalk disturbers. The identification of the crosstalk disturber is then used to perform crosstalk cancellation and spectrum management in a DSL system.

摘要： A combiner includes a circulator having a series of at least three sequential ports such that a signal input into a port is transmitted as an output at the next sequential port. A bandpass filter has a pass band and is coupled to a first port of the circulator such that a signal in the pass band that is input to the filter is output at a second port of the circulator. A third port of the circulator is configured to be coupled to an input signal that is out of the pass band such that a signal input at the third port is reflected as an output from the first port by the bandpass filter to then be output at the second port. The signals input at the first and third ports are combined at the second port. This configuration might be used in a cascaded fashion for combining multiple signals, together with low loss.
