Hongyu Zhao, Pingzhi Fan · IEEE Communications Letters · 2007
In this short note, an inadvertent omission in the above-named article by Y.-L. Chen, et al., [ibid., vol. 10, no. 7, pp. 549-551, July 2006], which results in a defect for the application of the coefficient test, is spotted and corrected.
