Title: Tps and pilot signal insertion apparatus in transmitter of ofdm system
Inventor: JUNG YEONG HAK
IPC: H04B1/76
Filed: 2000-08-17
Abstract: PURPOSE: A TPS and pilot signal inserting apparatus in a transmitter of an orthogonal frequency division multiplexing(OFDM) system is provided to facilitate implementation of a hardware by installing a ROM storing an index for a position for inserting TPS information and a pilot signal and its control circuit and storing only an index for the position for inserting the TPS information and the pilot signal in one OFDM frame. CONSTITUTION: A PRBS generator(10) initializes every bit by 1 in initialization and adjusting the first output value to be synchronized with the first active carrier in an OFDM symbol. A power booster(11) constantly outputs a power boosted pilot and a modulated TPS INIT bit for a PRBS reference stream WK. The first delay unit(12) delays an inputted IDATA() while the pilot is being modulated and outputs it. The second delay unit(13) delays a QDATA(), inputted image data, as long as a processing time and outputs it. A pilot position counter(14) locates a position of a continual pilot and a scattered pilot and uses them for a data multiplex control. A TPS counter(15) locates a position of the TPS pilot and controls a data multiplexing. A data multiplexer(16) selectively outputs a data carrier, a pilot and a TPS by using a control signal inputted from the pilot position counter(14) and the TPS position counter(15).
