Description

The SFLAF with LSTM model is a hybrid nonlinear acoustic echo cancellation (NAEC) system designed to remove echo from a microphone signal $d\left[n\right]$ using the far-end signal $x\left[n\right]$. It combines the Split Functional Link Adaptive Filter (SFLAF), which handles both linear and nonlinear echo components, with a Long Short-Term Memory (LSTM) network, which refines the residual error as a cascaded post-processing stage. Below, I will describe the architecture, its cascaded nature, and the mathematical formulation.
