An Efficient Timing and Frequency Synchronization Algorithm for OFDMA/TDD Mode in Downlink of IEEE 802.16-2004 and its Analysis
نویسندگان
چکیده
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 performance is evaluated in AWGN channel. This algorithm can be easily used for other OFDM based systems which receiver knows preamble by itself.

Analysis of OFDMA Downlink Frame Synchronization Method in Frequency Selective Fading Channels
IEEE 802.16-2004 and IEEE 802.16e-2005 standards specify OFDMA as a physical layer technique for fixed and nomadic BWA systems, respectively. OFDMA is very sensitive to time and frequency offsets. In this paper, a preamble based downlink frame synchronization method for OFDMA mode of WMAN is analyzed in frequency selective fading channels. Expressions for mean and variance of the metric are der...

The IEEE 802.16 standard for broadband wireless access was recently approved . It defines a physical layer for systems operating at frequency bands between 10 and 66 GHz, a medium access control (MAC) protocol and the convergence layers for carrying protocols such as IP, ATM and Ethernet. An IEEE 802.16 system consists of a base station and one or more subscriber stations. The duplexing scheme ...

This paper studies the channel asymmetric characteristic between a downlink and an uplink channel in orthogonal frequency division multiple access (OFDMA)/ time division duplexing (TDD) systems. To investigate the downlink and uplink channel asymmetry, we derive a propagation loss mo-del and a shadowing model taking into consideration geometrical information and inter-cell interference. Then, t...

Throughput performance and geographical service fairness of best effort service used for downlink of a 802.16e based TDD-OFDMA sectored cellular networks are evaluated in conjunction with different scheduling schemes and frequency reuse plans. The OFDM systems are based on two multiple access schemes, which are the OFDM-TDM and OFDMA, and considered scheduling schemes are round robin, max C/I, ...
