Patent KR-20020095021-A (KR)
IPC: H04B3/06
Filed: 2000-05-12
Abstract: A transmission system (14) broadcasts an information signal. Within the system (14), several components (e.g., 20-24) cause distortion to the information signal as the signal is processed and proceeds toward a broadcast antenna. Specifically, the group of distortion causing components (20-24) is identified as a first group, and is arranged in a sequence along a signal path (12) toward the antenna. The first group of components (20-24) performs various functions, including amplification, but each subjects the information signal to distortion shifts away from intended values. A second group of components (e.g., 28-32) modifies the information signal to compensate for the distortion shifts imposed by the first group of components (20-24). The second group of components (28-32) is located upstream of the first group of components (20-24). The second group of components (28-32) is arranged in a sequence to modify the information signal to compensate for the distortions in an order inverse to the occurrence of the distortions. Specifically, compensation for linear and non-linear distortions occurs in an order that is inverse to the occurrence of the linear and non-linear distortions.
