The present invention provides an apparatus and method for realize robust channel estimation in communicating system. A training sequence is configured that training symbols therein are insensitive to synchronization errors. In an embodiment of the invention, each training symbol in the time-domain is the circulating prefix form of a front training symbol. The training sequence can be inserted into the leading field or the loading field of a frame. According to the training sequence generated by a embodiment of the invention, the circulating prefix of a training symbolic is also the circulating postfix of a front training symbolic. The sequence can be used for robust channel estimation in SISO/MIMO communicating system. When the modulating symbols are used to generate training symbols, a same group of training sequence can be used for performing demodulation performance measuring and channel estimation.
