摘要:
A method for reducing fading channel signal data loss for serial data rates up to approximately 10 gigabits per second includes sequentially distributing serial data to multiple encoders. Individual data bytes are sent from the encoders to a convolutional interleaver. Each byte is distributed to an individual memory element of the interleaver in a received byte sequence. An address generator generates write and read addresses assignable to each memory element. Multiple shift registers have variably graduated lengths. The serial data is distributed between channels each having a different delay element created by shift register length differences. The delay elements are adjustable to correct data dropout due to daily atmospheric/channel changes. Fade detection signals are inserted before transmission and measured at a receiver. The fade signals help create erasure bits to improve decoding accuracy and adjust interleaver delay parameters.
