METHOD OF CONSTRUCTING WIRELESS NETWORK FOR ORTHOGONAL FREQUENCY DIVISION MULTIPLEX AND TERMINAL EMPLOYING OFDMA METHOD

摘要

Disclosed are a method of constructing a wireless network in an OFDM system using a single carrier and a terminal employing an OFDM method. The terminal discriminates a wireless network using multiple carriers from a wireless network using a single carrier through a downlink preamble, and acquires frame synchronization within a short period of time. In addition, the terminal determines a position of a CCS used by a cell/sector to which the terminal belongs. Furthermore, the invention proposes a pilot allocation method that can be applied to a wireless network using a single carrier, which obtains frequency diversity effects while effectively using resources. In the case where a wireless network operator uses N channels in N divided FFT domains, the actual number of channels is MN.
