  • Binary to quad phase generator
    Patent number: 11175394
    Abstract: A system for generating a pulse. In some embodiments, the system includes a processing circuit configured: to reverse the sign of a first group of two consecutive bits of a binary code word; to calculate three phase change bits, of a plurality of phase change bits, according to (?1)n k(n)/k(n?1) wherein k(n) is the nth bit of the binary code word, n being a positive integer ranging from 2 to 4, and to generate a phase modulation function for a pulse including a sequence of consecutive chips.
