Packet Format Design and Decision Directed Tracking Methods for Filter Bank Multicarrier Systems
Packetized data transmission is commonly used in wireless communication systems. Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the ...
