Abstract
We present a novel approach for blind frame length, frame offset, channel order and channel identification in null guard transmission scheme. We derived a deterministic maximum likelihood estimator for frame length and offset estimation and proposed computationally efficient suboptimum algorithms. These algorithms consider single and multi-channel systems. After frame length and offset are estimated, channel order and coefficients are found jointly by considering the maximization of a relative distance measure. Proposed method is shown to perform well leading to more efficient use of bandwidth in wireless systems.
