Optical communication transmitting apparatus and receiving apparatus
First Claim
1. An optical communication transmitting apparatus, comprising:
- an encoder, configured to encode and shunt an input signal, to generate multiple synchronous encoded signals;
a driver, configured to amplify the multiple encoded signals, to generate multiple drive signals; and
multiple light sources, configured to generate multiple synchronous optical signals when driven by the multiple drive signals;
wherein the encoder is configured to execute program instructions, wherein the program instructions comprise;
performing analog-to-digital conversion and encoding on the input signal, converting the input signal to an encoded signal, and converting the encoded signal to the multiple synchronous encoded signals;
wherein the encoder comprises a multistage NOT-gate cascade structure;
wherein each encoded signal passes through the same number of NOT gates from an input end of a first-stage NOT gate to an input end of a corresponding NOT gate of a last-stage NOT gate in the encoder;
wherein the number of Kth-stage NOT gates is greater than that of K−
1th-stage NOT gates in the encoder, each NOT gate in the K−
1th-stage NOT gates is connected to at least one NOT gate in the Kth-stage NOT gates, and K is an integer greater than 2.
