The problem with current communication systems lies in the interference and signal degradation caused by channel losses and distortion, particularly in high-speed data transmission scenarios. These challenges lead to errors and reduced data rates due to overlapping symbols and frequency distortions within the transmission channel. To tackle this, the adaptive equalizer introduced in this invention adjusts dynamically to varying data rates while compensating for Inter Symbol Interference (ISI). By incorporating advanced control mechanisms and innovative spectral balancing techniques, it effectively mitigates these issues without relying on complex High Pass Filters (HPFs), thereby optimizing signal integrity, reducing power consumption, and simplifying circuit design for more reliable communication performance across different applications.
