SIMO\u2010OFDM systems have been widely used in wireless communications. Compared to those approaches using training sequences, blind channel estimation methods for SIMO\u2010OFDM systems have the advantage of saving bandwidth and improving energy efficiency and system throughput. As far as blind channel identification is concerned, it is known that zero padding (ZP)\u2010based single\u2010input single\u2010output (SISO)\u2010OFDM systems have desirable features compared to conventional cyclic prefix (CP)\u2010based SISO\u2010OFDM systems. However, it is yet unknown whether ZP\u2010 or CP\u2010based SIMO\u2010OFDM systems are favourable for blind channel estimation. To investigate this problem, we first propose a short\u2010data effective method for blind channel estimation for ZP\u2010based SIMO\u2010OFDM systems. Then we analyse a number of issues surrounding blind channel estimation for ZP\u2010 and CP\u2010based SIMO\u2010OFDM systems. The issues brought up in the paper have not been discussed in the existing research. The significance of our investigation is that it provides a deep insight into blind channel estimation for ZP\u2010 and CP\u2010based SIMO\u2010OFDM systems.
