摘要： A transceiver comprising:



a transmitter configured to transmit a signal comprising differential voltages to at least a first terminal and a second terminal;
at least one receiver;
a controller configured to provide control signals to the transmitter to cause the transmitter to transmit symbols, wherein each symbol comprises a predefined set of said differential voltages including at least a positive differential voltage and a negative differential voltage; and
a signal balance module configured, for one or more symbols, to:

determine a first duration of the positive differential voltage of said one or more symbols;
determine a second duration of the negative differential voltage of said one or more symbols;
based on determination of a difference between the first and second durations, provide for control of the controller or control of the transmitter to reduce the difference between the first and second durations in a further symbol relative to the one or more symbols.

摘要： The present disclosure provides computer-based methods and a system for synthesizing a NoC that advantageously generate balanced NoC topologies without end-to-end fairness or local credit-based arbitration, and improve NoC performance when destination device bridge ports support only one incoming physical link per channel. More particularly, a clock domain is assigned to certain routers that satisfies the minimum frequency for the router while reducing clock domain transitions to neighboring routers, and the traffic flows received by these routers are balanced based on the traffic flow packet rates.

摘要： Disclosed is receiver for a noise limited system. A front-end circuit amplifies and band-limits an incoming signal. The amplification increases the signal swing but introduces both thermal and flicker noise. A low-pass band limitation reduces the thermal noise component present at frequencies above what is necessary for correctly receiving the transmitted symbols. This band limited signal is provided to the integrator circuit. The output of the integrator is equalized to reduce the effects of inter-symbol interference and then sampled. The samples are used to apply low frequency equalization (i.e., in response to long and/or unbalanced strings of symbols) to mitigate the effects of DC wander caused by mismatches between the number of symbols of each kind being received.

摘要： A transceiver device comprising transceiver circuitry (5) coupled to one or more antenna ports (2; 2′) by a balun arrangement (Lb, Lu; Lu′). For each of the antenna ports (2; 2′) an antenna switch (Ta; Ta′) is present having an antenna enabling input (4; 4′) and being arranged to connect an unbalanced coil (Lu; Lu′) from the balun arrangement (Lb, Lu; Lu′) to the antenna port (2; 2′) and a ground port (3). Also an electro-static discharge (ESD) protection circuit is provided with an ESD switch (Te; Te′) arranged to connect the antenna port (2; 2′) to the antenna enabling input (4; 4′) of the antenna switch (Ta; Ta′). The ESD switch (Te; Te′) has an ESD switch control input (A) connected to an ESD trigger arrangement (Rtrigger).

摘要： An electrical balance duplexer (EBD) may be used to isolate a transmitter and receiver that share a common antenna. By using impedance gradients to provide impedances that cause balance-unbalance transformers (balun) of the EBD to cut-off access to the common antenna rather than duplicate the antenna impedance, the EBD is balanced. Such cut-offs may have a lower insertion loss than an EBD that merely duplicates the antenna impedance to separate the differential signals of the receiver/transmitter from the common mode signal.

摘要： The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for cancelling a self-interference (SI) signal in a communication system supporting a full-duplex scheme is provided. The method includes estimating an SI channel, performing a pre-filtering operation on a transmission signal based on the estimated SI channel, generating copied-SI signals based on the estimated SI channel, and cancelling an SI signal based on the copied-SI signals, wherein the pre-filtering operation includes an operation for decreasing a number of SI signals.
