Abstract—Channel estimation is a crucial technique in wireless communication, and pilot pattern design is an essential procedure to realize PSA-OFDM (pilot symbol assisted orthogonal frequency division multiplexing). In this paper, we researched on the constrained conditions of pilot pattern such as the number and the interval of pilot symbols. Then, all kinds of the pilot patterns and usage scenarios are summarized roundly. Finally, we put forward some problems which are significant but have not been solved well up to now.

Index Terms—pilot patterns, channel estimation, constrained conditions, PSA-OFDM
