“…In addition, we show that by using a different pulse shape that trades off ISI with the IAI, gains may be achieved practically for free. Although there is a large volume of prior research in the design of quasizero ISI practical pulse shapes that conform to various criterion such as spectral mask requirements, robustness to timing jitter, and peak-to-average power ratio (e.g., [2,[14][15][16][17][18] and references therein), to our knowledge, this is the first time that pulses have been designed with this criterion of lowering the IAI.…”

The performance of MIMO systems with intentional timing offset between the transmitters has recently been the focus of study of different researchers. In these schemes, a nonzero (but known) symbol timing offset is introduced between the signals transmitted from the different transmitters to improve the performance of MIMO systems. This leads to a reduction in Interantenna Interference (IAI), and it is shown that an advanced receiver can utilize this information to extract significant performance gains. In this paper, we show that this transmission scheme may be used in conjunction with different kinds of receivers including ZF, MMSE, and sequence detection-based receivers. We also consider the design of novel pulse shapes that reduce the IAI at the expense of slightly higher intersymbol interference (ISI) and show that additional gains may be achieved.
