Data rate and data transfer rate can refer to several related and overlapping concepts in communications networks: . Achieved rate. Bit rate, the number of bits that are conveyed or processed per unit of time . Data signaling rate or gross bit rate, a bit rate that includes protocol overhead; Symbol rate or baud rate, the number of symbol changes, waveform changes, or signaling events across ...

CSIT error considerate delay-sensitive user access systems are provided in a multi-user OFDMA environment comprises a user delay sensitivity tracking component, a CSIT estimating component, a system queue state tracking component and a cross layer scheduling component. The techniques assume heterogeneous users with respect to delay and assume that CSIT information includes error, and optimally allocates broadcast resources, e.g., power, subcarriers and data rate, based on such assumptions.

Equalizer architecture

InactiveUS20050201455A1Increase data rateComponent with highMultiple-port networksDelay line applicationsData rateEngineering

An equalizer is divided between two tapped delay lines. One half of the sampled data is passed along one delay line, and the other half of the sampled data is passed along the other delay line. Delayed samples are passed to two summing circuits, and the output is formed from the two summing circuits alternately. This structure has the advantage that, by doubling the number of components, each component effectively only needs to operate at half the rate which would be required in a conventional structure. This allows the equalizer to operate successfully with signals at higher data rates.

Data transmission method and equipment

InactiveUS6563789B1Network traffic/resource managementError preventionTransmission protocolMobile business

The invention relates to a data transmission method and equipment in a telecommunication system, particularly in a situation where the maximum data rate of a traffic channel is equal to one user data rate at a terminal interface. A mobile station inserts terminal interface status information in redundant parts of redundant user data elements of an end-to-end transmission protocol and sends them through the traffic channel without that the status information raises the data rate. If no user data elements are received at the terminal interface, auxiliary frames, in which the terminal interface status information can be transmitted, are generated. A mobile services switching centre separates the terminal interface status information from the redundant data elements or auxiliary frames at the receiving end.

Femto user resource distribution method based on dense distribution

ActiveCN105554771ANetwork planningAlgorithmData rate

The present invention relates to the technical field of wireless communication, and particularly relates to a femto user resource distribution method based on dense distribution. According to the optimal solution of a function, the grouped femto users are subjected to resource distribution, wherein the solution of the optimal solution of the function comprises a step of substitute a whole user grouping problem into a lingo mathematical platform, a step of determining all feasible solutions of grouping optimization according to a constraint condition, a step of establishing a simplex tableau and obtaining the test number corresponding to each feasible solution according to the obtained feasible solutions, a step of using a direct solution program to process model equality constraint according to the characteristics of the lingo mathematical platform, judging a model type and calling a branch boundary determination program to obtain the optimal solution of the function combined with the simplex tableau. The femto users are grouped according to the strength of the interference between femto groups, the same-layer interference in each group of femto is minimized, the total data rate of a femto cell is maximized, and the solution of the grouping optimization is obtained.
