Improving time-delay estimation and multipath resistance is one of the most important drivers for designing new satellite signals, together with noise and multiple access interference reduction. This chapter proposes a theoretical analysis for designing new spreading waveforms that can achieve this multiform problem. Following a systematic approach for designing new signal-in-space waveforms has lead to an implementable mathematical optimization problem to improve time delay estimation for the additive white Gaussian noise channel with two-ray multipath (MP) propagation. In this scenario, minimizing the Gabor bandwidth with a constraint on the sidelobe levels is shown to represent an effective optimization criterion for designing spreading signals with higher robustness against MP. Starting from the generic waveform formulation of the signal as a cardinal interpolation of the cardinal sine function, the proposed band-limited non-binary signal represents an effective way to optimize the performance following the Gabor bandwidth analysis.
