Abstract
A preamble reception apparatus and a reception method for extending a range of a base station are provided. The apparatus includes a preamble symbol unit data generator for receiving preamble symbols, a first fast Fourier transformer for fast Fourier transforming each output of the preamble symbol unit data generator, a first sequence generator for generating a preamble sequence, a coverage extension detector configured to calculate symbol power of each of the preamble symbols, calculate a non-coherent sum for each consecutive preamble symbol, combine the non-coherent sums, and detect a maximum energy value among the non-coherent sums and a first delay value (DF) of the preamble symbols having the maximum energy value, a delay ambiguity detector configured to calculate power for two consecutive preamble symbols, and estimate a second delay value (DT) of the preamble symbols, and a preamble determiner for determining whether a preamble is received.
