摘要
A method for performing cell search in an orthogonal frequency division multiple access (OFDMA) based cellular communication network in which a primary synchronization channel (P-SCH), and optionally a secondary synchronization channel (S-SCH), carries cell search information. A downlink signal is received containing P-SCH symbols. The P-SCH symbols are processed to obtain an initial detection of frame timing, orthogonal frequency division multiplexing (OFDM) symbol timing, a cell identifier (ID), a frequency offset, and a cell transmission bandwidth. Optionally, an OFDM symbol timing self-check and error correction is then performed.
