DIVERSITY REPETITION FOR LOW RATE MODE IN IEEE 802.11AX

摘要

Signal processing for the Low Rate (LR) mode in IEEE 802.11ax. The LR mode can have a code rate lower than MCSO by applying repetition (in the frequency and/or time domain) in order to increase demodulation performance through diversity. Each block of data is split in two halves, repeated and the four resulting half blocks are then assembled in time/frequency to provide the best diversity gain.
