Apparatus and method for transmitting a preamble and searching a cell in an OFDMA system |
摘要 |
An apparatus and method for generating a preamble and searching a cell using the generated preamble in an orthogonal frequency division multiple access (OFDMA) system. Q cyclic shift values and P pseudo-random noise (PN) codes are used to distinguish N cells. One of the P PN codes is cyclically shifted according to one of the Q cyclic shift values and therefore a preamble is generated. Because a relatively small number of PN codes are used, the memory capacity of a mobile terminal for storing the PN codes is saved and a cell search error is reduced.
