摘要： A method and system for the design and implementation of an optimally factored filter is presented. Pairs of angle values are organized in pairing candidates and a threshold is defined to indicate an upper bound on the number of pairing candidates. A first pairing candidate is exchanged above the threshold with a second pairing candidate below the threshold and a matrix is generated based on the pairing candidates below the threshold. A lowest predicted total quantization cost between all pairing candidates represented within the matrix is determined and the pairing candidates that result in the lowest predicted total quantization cost are used to determine the coefficients of the filter.

摘要： An input signal to a filter device is allowed to be written into one of a plurality of sequentially connected cells if the input signal is not the zero-valued sample. Each cell receives the input signal and multiplies the input signal by one of a plurality of weight coefficients. The input signal is stopped to be written into any of the cells if the input signal is the zero-valued sample. A result of a filtering operation is output from the last cell.

摘要： A digital filter is provided for radio communication processing capable of dynamically modifying the characteristic and simultaneously processing a plurality of systems. In the digital filter, calculation core groups capable of modifying function are arranged and connected to one another by an input interface unit and an output interface unit. When the communication mode is modified, the number of calculation resources to be used and setting contents are decided according to the setting candidate of the filter characteristic required and the calculation resource empty state. According to the decision, functions of the respective parts are modified to perform a predetermined operation control, so as to flexibly modify the limited multiplication/addition calculation resource calculation tap quantity, the operation clock, and the connection relationship, thereby enabling simultaneous and parallel execution of a plurality of different finite impulse response (FIR) filter processes and simultaneous and parallel execution of a plurality of filter processes.

摘要： A reconfigurable digital signal filter processing unit for use in a communication device is provided. The reconfigurable filters processor can implement different filter topologies to adapt to a range or wireless technology characteristics. The reconfigurable filter processor comprises a plurality of filter blocks whose inputs can be selected based on the desired configuration of the filter. Each filter block applies a transfer function to a received signal to achieve a desired filtering function.
