书文提出了一种称为平均反馈(AF)的新算法．该算法利用两个相邻的 0FDM符号之间的荧联信息对LS算法的估计结果进行平均和反馈．以减少离斯白噪声岛子信道间干扰(1cI)对信道估计结 果的影囔。-The book article proposed one kind is called the average to feed back (AF) the new algorithm. This algorithm uses two neighboring between the 0FDM ma

A 16-QAM signal X, whose power is normalized as unity, is transmitted with OFDM over the discrete-time channel model h which has been used in Homework #2 and #3. As depicted in the below figure, the transmitter (TX) is now equipped with an N-point ID

Abstract—Diagonal Bell Laboratories Layered Space-Time (DBLAST) structure offers a low complexity solution to realize the attractive capacity of Multiple-input and multiple-output (MIMO) systems. In this paper, we apply D-BLAST in orthogonal fr
