摘要
Provided are an apparatus and method for measuring a carrier-to-interference-and-noise ratio (CINR) using down-link preambles. More particularly, provided are an apparatus and method that measure CINRs according to a plurality of logical bands in a downlink band-adaptive modulation and coding (AMC) channel mode zone using preambles and determine whether or not to switch to another channel mode or logical band on the basis of the CINRS. According to the apparatus and method, it is possible to easily measure a plurality of CINRs and switch to a better channel mode or another logical band using the measured CINRs. Consequently, the optimum channel environment can be maintained.
