FRAME SYNCHRONIZATION METHOD AND RECEIVER FOR COMMUNICATION MODEM USING THE SAME |
摘要 |
Disclosed are a frame synchronization method and a receiver for a communication modem using the same. The frame synchronization method includes performing a correlation operation between a reception data stream and a preamble to output a synchronous signal; and computing correlation values between spreading codes and a reception data stream synchronized with the synchronous signal, wherein a maximum value of the computed correlation values is compared with a preset threshold value, and the outputting of the synchronous signal is performed again when the maximum value is smaller than the preset threshold value.
