Orthogonal Frequency Division Multiplexing Timing Synchronization in Multi-Band Orthogonal Frequency Division Multiplexing Ultra-Wideband Systems
Problem statement: MB-OFDM UWB systems have attractive features and received a great attention. It has the capability of sending/receiving data at rates in access of 100 Mbits sec. Owing to the sensitivity of OFDM systems to synchronization errors, a fast synchronization algorithm is required to discern for the start of OFDM symbol. Existing approaches to OFDM time synchronization rely on their...
متن کاملJoint Timing Synchronization and Channel Estimation in Uplink of Time Domain Synchronous OFDMA
Multiple users TDS-OFDMA has been proposed based on time domain synchronous orthogonal frequency division multiplexing (TDS-OFDM). This multiple access schemes used mostly in mobile broadband wireless access scheme in uplink transmission due to the multiple user interference in timing offset and frequency offset problems. In this paper we are focusing on timing synchronization and channel estim...
متن کاملSynchronization sensitivity of multicarrier systems
In this paper, we give an overview of the sensitivity of a number of multicarrier systems to carrier and clock synchronization errors. A comparison is made between orthogonal frequency division multiplexing/multiple access (OFDM(A)) and two combinations of the orthogonal multicarrier technique and the code-division multiple access (CDMA) technique, i.e., multicarrier CDMA (MC-CDMA), where the s...
متن کاملAn Efficient Timing and Frequency Synchronization Algorithm for OFDMA/TDD Mode in Downlink of IEEE 802.16-2004 and its Analysis
Timing and frequency synchronizationsare the important tasks in receiver. In this paper, an efficient timing and carrier frequency offset (CFO) estimation algorithm for orthogonal frequency division multiple access/ time division duplexing (OFDMA/TDD) mode in IEEE 802.16-2004 standard (WiMAX) is represented. This method has high performance and jointly estimates timing error and CFO. The perfor...
