OFDM BASED WIRELESS BACKHAUL SYSTEM FOR IMPROVING FRAME TRANSMISSION QUALITY AND LATENCY

摘要

The present invention relates to a method of transmitting a signal of a physical layer and a MAC layer for effectively aggregating and transmitting Ethernet packets in a wireless backhaul network for a wireless LAN. Since the Ethernet packets have various sizes according to application information, in the present invention, a frame is aggregated taking a sequence and the size into consideration instead of just sequentially aggregating packets in the backhaul network. In addition, an aggregated jumbo frame is OFDM modulated in the physical layer, since PAPR (peak amplitude to average power ratio), which is a problem of the OFDM modulation when size of the jumbo frame is large, can occur, in the present invention, a scheme for decreasing the PAPR by forcibly applying an amplitude distortion in a frequency domain.;COPYRIGHT KIPO 2015
