“…(Quasi-)Pilot GNSS signals have been designed [12]- [15] or re-designed [16] to address emerging mass-market user needs. So far, these designs have focused on the use of very low data rates (0-50 Hz) to avoid sensitivity loss due to data symbol transitions, i.e., they enhance the GPD.…”

“…Such battery-powered devices have often stringent requirements on power and energy consumption, which do not align well with the considerable power demand of the GNSS technology [1]. Galileo Evolution working groups are recognizing the importance of providing signals that economize receiver processing resources [2]. In fact, enabling low power dissipation at the receiver has become an important signal design driver.…”

The use of a 1-bit analog-to-digital converter (ADC) with low sampling rate (1-3 MHz) offers a drastic reduction of power consumption for mass-market receivers of the global navigation satellite system (GNSS). Given the low bandwidth of such a front-end, we propose pulse shaping at the satellite to avoid the significant bandlimiting loss currently experienced by the rectangular (REC) pulse. The disadvantages of a nonbinary pulse are the reduction of the high power amplifier (HPA) efficiency, and that a 1-bit receiver can neither sample nor replicate the pulse perfectly. Nevertheless, our analytical and numerical results show that there are pulse shapes with a performance gain of 0.3 to 1.1 dB in terms of correlator output signal-to-noise ratio (SNR) compared with the REC pulse, due to lower combined losses of bandlimiting, sampling, quantization, and replica mismatch. We conclude that transmit pulse shaping may be a simple way forward to improve the navigation performance for mass-market GNSS users.
