Abstract
A receiver performing a stable operation in a burst mode is provided. The receiver transmits packet data using a preamble, and has good acquisition performance so that a synchronization part converges on a preamble interval. For the acquisition performance, the receiver senses the carrier of a received signal, detects a rough location of a burst, and in response to the result of carrier sensing, performs coarse gain control, symbol timing compensation, and frame synchronization. Then, if the frame synchronization is completed, in response to the result of frame synchronization, the receiver performs fine gain control, equalization of the signal, and carrier recovery.
