Abstract :
This paper presents a high-frequency low-noise equalization method using an adaptive analog FIR filter and an error detection scheme with reduced high-frequency noise amplification. The error signal for training is calculated by comparing the spectrum energy of the training signal with the equalized signal. The equalizer has been simulated to work successfully in 125 Mbps data transmission for 200 m unshielded twisted pair category 5 (UTP5) cables
