In this paper, we investigate the timing and carrier
frequency offset (CFO) synchronization problem in decode and
forward cooperative systems operating over frequency selective
channels. A training sequence which consists of one orthogonal
frequency-division multiplexing (OFDM) block having a tile
structure in the frequency domain is proposed to perform synchronization.
Timing offsets are estimated using correlation-type
algorithms. By inserting some null subcarriers in the proposed tile
structure, we propose a computationally efficient subspace decomposition-
based algorithm for CFO estimation. The issue of optimal
tile length is studied both theoretically and through simulations.
By judiciously designing the tile size of the pilot, the proposed
algorithms are shown to have better performance, in terms of
synchronization errors and bit error rate, than the time-division
multiplexing-based training method and the computationally demanding
space-alternating generalized expectation-maximization

现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,同步(时间/频率同步)和信道估计,以及频率偏移的估计等一系列代码.希望大家能从中得到你需要的东西.
(Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel estimation, as well as the frequency deviation of the estimated range of the code. I hope that everyone will be you need.)
