Echo Cancellation Noise Reduction system from NXP Semiconductor addresses the issues that can occur when using a hands-free phone setup in a vehicle.
Most of the advance
echo cancellation system uses adaptive filtering techniques.
The topics include digital signal processing (DSP) fundamentals and implementation considerations, the design and implementation of finite impulse response (FIR) and infinite impulse response (IIR) filters, frequency analysis and the discrete Fourier transform, adaptive
echo cancellation, speech signal processing, and digital image processing.
The patent-pending solution will also provide multi-channel acoustic
echo cancellation (AEC) and suppress room ambient reverberation; all these contribute to significant voice command accuracy improvement.
Adaptive filtering algorithms have gained popularity and proven to be efficient in various applications such as system identification, channel equalization, and
echo cancellation [1-4].
The JBL speaker phone works with Bluetooth-enabled phones via a built-in microphone, while the sound is enhanced through digital sound processing and
echo cancellation.

The Compact Class transmitter family includes translators/transposers and single-frequency network (SFN) gap-fillers with adaptive
echo cancellation, providing a full range of Harris transmission solutions that allow DTV broadcasters to cover their terrestrial markets.
