A Novel PN Complementary Pair for Synchronization and Channel Estimation
نویسندگان
چکیده
In this paper, a novel pseudo-random noise complementary pair (PNCP) is proposed and adopted as the guard intervals in the time-domain synchronous OFDM (TDSOFDM) system. The proposed PNCP has nearly ideal aperiodic auto-correlation property and inherits the differential property of the PN sequence. Simulations demonstrate the proposed TDSOFDM system padded with PNCP could achieve better performance in both synchronization and channel estimation than the conventional TDS-OFDM system. key words: TDS-OFDM, PN complementary pair, aperiodic auto-correlation, synchronization, channel estimation

Carrier frequency offset estimation method for 2 × 1 MISO TDS-OFDM systems
In time-domain synchronous (TDS)-orthogonal frequency division multiplexing (OFDM) systems, a pseudo noise (PN) sequence is inserted instead of the cyclic prefix. The PN sequence is used not only as a guard interval but also as a training sequence for channel estimation and synchronization in the time domain. Recently, research studies on 2 × 1 multi input-single output (MISO) TDS-OFDM systems ...

متن کاملChannel Estimation Based on Full ISI Interference Cancellation in TDS-OFDM System
By adopting the same block-type pseudo-random noise (PN) sequences as the guard interval (GI) as well as the training sequence in time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) system, the received PN signal will be corrupted by the adjacent OFDM symbol sequences interference. A novel channel estimation algorithm is introduced through the received PN data and the ...
