A digital front-end circuit is disclosed. In one aspect, the circuit includes a filtering block for filtering received data. The filtering block has a first filter branch for filtering the received data in a first frequency band and a second filter branch for filtering the received data in a selected second frequency band. The second filter branch is in parallel with the first filter branch, is programmable and includes a block for resampling the received data. The front-end circuit also includes a circuit for performing synchronization and spectrum sensing on the received data, which is in connection with the output of the filtering block. The front-end circuit also includes a controller block for controlling the filtering block and the synchronization circuit.

Digital front-end circuit and method for using the same

Presented is a method of managing the operation of a system including a processing subsystem configured to run a multimedia application and a telecommunication subsystem. The method includes determining telecom environment conditions, and selecting a working point from a plurality of predetermined working points. The selecting is based at least in part on the determined environmental conditions. The method also includes setting control parameters in the multimedia application and/or the telecommunication subsystem to configure the system to operate at the selected working point, and operating the system at the selected working point.

Method for operating a combined multimedia-telecom system

Disclosed is a method for managing the operation of a telecom system, and minimizing the energy to be drained from a power supply. According to the method, a rate constraint and telecom environment conditions are determined. Then, a working point is selected a plurality of predetermined working points based on the rate constraint and the telecom environment conditions. The telecom system is operated at the selected working point by setting corresponding control parameters.
