Abstract: PROBLEM TO BE SOLVED: To provide a system having solved a problem, wherein since respective spread signals output by a spreading system is based on two or more data signals, when using such a spreading system, several separation processes of the data signals must be performed before spreading, but the complexity of the spreading system is increased, when a separation processing operation increases the complexity of the data signal, and a desired operation cannot be attained.
SOLUTION: A spreading system spreads two data signals. The system produces a filtered signal, based on one of the data signals and an output signal that is based on both of the data signals. In one example, a spreading system is used to perform QPSK spreading of two data signals, the QPSK spreading actually including separation processing of the two data signals. Such a separation control can include a filtering and/or a gain control.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that since each spread signal output by a spreading system may be based on more than one data signal, any separate processing of the data signals must be performed before spreading when existing spreading systems are used, but in a case where the separate processing operation increases the complexity of the data signal, the resulting increase in the complexity of the spreading system that may be required may render the desired implementation impracticable.
SOLUTION: Two data signals are spread. The system produces a filtered signal that is based on one of the data signals and an output signal that is based on both of the data signals. In one example, a spreading system is used to perform QPSK spreading of two data signals, including separate processing of the two data signals, in a practical manner. Such separate control may include filtering and/or gain control.

Abstract: A system for digital filtering includes a set of logic gates, a state storage, and a multiplexer. The state storage includes two or more storage banks and may also include combinatorial logic and/or at least one lookup table. In one application, a filtering operation according to a finite-impulse-response filter coefficient vector is performed without runtime multiplications. Applications to symmetric and antisymmetric filter coefficient vectors are described, as well as applications to filter coefficient vectors of arbitrary odd or even length.
