overlay
function Px=overlay(N,omega,A,sigma,num)
OVERLAY Forms multiple power spectral density estimates.
-------
USAGE Px=overlay(N,omega,A,sigma,num)
Calculates the periodogram using an ensemble of realizations
of a process consisting of a sum of complex exponential in
white noise.
N : length of the signal
omega : vector containing the sinusoid frequencies
A : vector containing the sinusoid frequencies
sigma : the variance of the white noise
num : size of the ensemble (number of periodograms)

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
