PROBABILISTIC AMPLITUDE SHAPING APPLIED TO PAPR REDUCTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18695251 titled 'PROBABILISTIC AMPLITUDE SHAPING APPLIED TO PAPR REDUCTION
The apparatus described in the patent application includes memory that stores probabilities of transitions between modulation symbols, which results in a lower peak-to-average power ratio compared to equal probabilities of transitions. The distribution matcher circuitry processes an input bit sequence into a symbol sequence, ensuring that the frequencies of transitions between symbols align with the stored probabilities. A channel coder generates parity bits from the symbol sequence, while grouping circuitry assigns symbols into groups and multiplication circuitry multiplies these groups with corresponding parity bits. This innovation aims to optimize power efficiency and data transmission reliability in communication systems.
