WebApr 9, 2024 · An essential precondition for the effective use of low-frequency spread-spectrum acoustic signals is their synchronous acquisition. Due to the low bit rate that low-frequency spread-spectrum signals have, the length of the spreading spectrum code and the number of intra-chip carriers need to be precisely designed to balance the acquisition … Webof the spectrum at low power —is more efficient. The concept is counterintuitive: instead of carving a pie into a finite number of small slices, the technology allows a larger sharing of the whole pie by permitting an all but un-limited number of individuals to take barely noticeable bites. Although spread-spectrum radios use more bandwidth ...
