Adaptive Volterra channel equalisation with lattice orthogonalisation

Adaptive multichannel decision feedback equalization for volterra type nonlinear communication channels

“…The probability of error evaluations were conducted using 10 6 samples. Initially, the channel was equalized with a third-order Volterra feedforward equalizer (VFFE) [21]. Then, the feedback channels were incorporated sequentially and multichannel stages were added until no further improvement in the mean squared error is achieved.…”

Nonlinear System Identification Using Deterministic Multilevel Sequences

“…Typical examples include trying to relate two signals whose significant spectral components do not overlap, and satellite communication channels [1], [4], [15] where amplifiers are operated near saturation, or magnetic recording channels [16]. The truncated (or "doubly finite") Volterra series representation constitutes an appealing nonlinear system model, as the output is linearly dependent on the kernel parameters, hence making the identification process mathematically tractable [10], [11].…”
