feed forward equalization 专利
Feed forward equalizers (FFE) are a type of signal processing technique used in communication systems to improve the quality of the transmitted signal. FFEs are used to compensate for signal distortion caused by channel impairments such as attenuation, dispersion, and noise.
An FFE works by using a reference signal that is delayed and attenuated to match the distortion in the received signal. The delayed and attenuated signal is then subtracted from the received signal, leaving only the desired signal. The FFE adjusts the delay and attenuation of the reference signal to match the changing characteristics of the channel and provide a more accurate equalization of the signal.
FFE is commonly used in digital communication systems, such as Ethernet, to improve the signal quality and increase the data transmission rate. It is also used in wireless communication systems to compensate for multipath fading and other signal distortions.
Overall, feed forward equalizers are an important tool in the signal processing toolbox for improving the quality and reliability of communication systems.
