Apparatus and method for generating a preamble sequence in an OFDM communication system

摘要

Preamble sequence of length n' mapped to n subcarriers among m' subcarriers, on one-to-one basis, is generated, where n is less than m. Components with preamble sequence are assigned to n subcarriers, based on one-to-one mapping and null data are assigned to remaining subcarriers of m subcarrier excluding n subcarriers. Assigned result is transformed into time domain data using inverse fast Fourier transform (IFFT). An independent claim is also included for preamble sequence generation apparatus.
