Abstract: PURPOSE: A communication method for sharing characteristic information by using a preamble, a method for generating a preamble, and a communication system which is applied with the same are provided to efficiently share the characteristic information of a wireless telecommunication system by minimizing an amount of an information bit. CONSTITUTION: A first repetitive pattern about a real number and a second repetitive pattern about an imaginary number at a preamble are determined in a time domain(810). The first repetitive pattern and the second repetitive pattern depend on subcarrier selection or the subcarrier sequence of selected subcarriers and the allocation of a subcarrier phase value. Two or more subcarriers are selected from a plurality of subcarriers(821). A subcarrier sequence and subcarrier phase value of the preamble, which is mapped in two or more subcarriers, are determined(822,823). A transmitter generates the preamble by mapping the subcarrier sequence and the subcarrier phase value in the selected subcarriers(830). The preamble is transmitted(840).

Abstract: PURPOSE: A method and apparatus for evaluating the effect of an electromagnetic wave near a base station on a human body are provided to obtain the same measurement effect using one minute measurement which is reduced by 1/6 of the average time presented in an ICNIRP(International Commission on Non-ionizing Radiation Protection) when electromagnetic wave intensity is measured for evaluating a human body exposure amount. CONSTITUTION: Electric field strength for 6 minutes is measured at a metering point which is an arbitrary metering point for obtaining the whole body average of an influence on a human body(S410). A mean value for 6 minutes and a mean value for a first time or below 6 minutes are calculated and compared based on the measurement result of the electric field strength measured for 6 minutes. A first standard deviation is the deviation of the mean value for 6 minutes and the mean value for the first time and whether the first standard deviation is below a threshold(S420).
