Hybrid automatic repeat request combining method in orthogonal frequency division multiplexing system
摘要:
The present invention provides a HARQ (Hybrid Automatic Repeat Request) combining method in an OFDM (Orthogonal Frequency Division Multiplexing) system, which adopts improved Chase combining method weighted by SNR and variance of SNR to realize HARQ combining. The method can improve system performance in processing power and time delay, particularly in low SNR environment, and will not make the system more complex.
