Assignee: ONE MEDIA, LLC
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A receiver to be used in a broadcast network, the receiver comprising:
a memory storing program instructions; and
a processor, upon executing the program instructions, configured to:
receive an initial Orthogonal Frequency Division Multiplexing (OFDM) symbol of a frame control of a preamble of a broadcast frame;
receive a second OFDM symbol of the frame control and a third OFDM symbol of the frame control,
wherein the initial OFDM symbol is a synchronization symbol configured to enable synchronization and initial channel estimation at the receiver,
wherein the initial OFDM symbol is based on a first sequence modulated by a pseudo-noise (PN) sequence and the first sequence is generated based on a Zadoff-Chu (ZC) root index value, and wherein the PN sequence is reset at a start of the preamble, and
wherein the second OFDM symbol and the third OFDM symbol are generated based on the ZC root index value; and
use the initial ODFM symbol for coarse synchronization and the initial channel estimation;
determine a cyclic shift associated with the subsequent OFDM symbol, wherein the cyclic shift is based on frame configuration information associated with the broadcast frame and wherein the frame configuration information comprises parameters of the preamble; and
use the second OFDM symbol and the third OFDM symbol for acquisition of one or more subsequent OFDM symbols of the preamble.
