    • ...SI signals perform well numerically and in noise, in Section V we borrow a metric, discussed in detail in our recent work [39], that we refer to as localized coherence (LC)...
    • ...As discussed in [39], it is not the high mutual coherence or RIP of the sensing matrix that ultimately drives the channel estimation performance...
    • ...What is important to remark is that we can find SI inputs and guarantee unique recovery even for model classes with vanishing . SI designs that further ensure numerical stability and resilience to noise can be singled out in this wider class, as we show in Section V and explain in more detail in [39]...
    • ...Denoting as the column of associated with the grid point indexed by and path parameters , we call localized coherence (LC) (see [39]):...
