发明名称 Adaptive pre-equalization apparatus for correcting linear distortion of a non-ideal data transmission system
摘要 An adaptive apparatus (10) for compensating a linear distorting action to an information signal within a non-ideal transmission system (12). Within the system (12), an information signal proceeds to a transmitter (34) that has an amplifier (62). A sample signal is coupled-off from the transmitter (34). The linear distorting action of the system (12) includes shifting of at least one aspect of the signal away from its intended value. A linear pre-equalizer (54), located along a signal stream of the information signal to the transmitter (34), pre-equalizes the information signal. An adaptive equalization determination (70), connected to receive the sample signal and the information signal outside of the signal stream to the transmitter (34), determines an amount of pre-equalization required from the linear pre-equalizer (54) to compensate the linear distorting action of the system (12). The pre-equalization by the linear pre-equalizer (54) is modified in response to the determination by the adaptive equalization determination (70).
