In this paper, we propose a low complexity solution to the compensation of nonlinear distortion of loudspeaker systems.
Nonlinear distortion can, in general, be compensated by a linearization system that uses the Volterra kernel.
The main problem with this approach is the huge computational complexity associated with convolving the input signal to the 2nd-order Volterra kernel.
The subband adaptive Volterra filter (SBAVF) offers lower computational complexity while maintaining the compensation performance.
However, the reduction in computational complexity is modest.
Our solution is assigning different tap lengths for each sub-band. Experiments show that it significantly reduces the computational complexity
while maintaining comparable compensation performance. |
