ABSTRACT:
A method of pulse-position modulation in a spread-spectrum communication system, which is capable of transmitting more than one bit per received and recognized chip sequence in a system in which an entire chip sequence is required to produce a correlation pulse. A framing pulse window in which a framing pulse may be received, and a plurality of data pulse windows in which a data pulse may (or may not) be received. The delay between the framing pulse window and the first data pulse window may comprise an entire chip-sequence duration, while the delay from one data pulse window to the next may be less. A method of pulse-position modulation with more than one spread-spectrum code. A second transmission medium (such as a second spread-spectrum code) on which a data pulse may (or may not) be received. Each possible choice, for the data pulse, of delay time and transmission code may represent a separate set of multiple data bits. A method of transmitting signals in a spread-spectrum communication system in which a spread-spectrum chip sequence may be interrupted with reduced noise. The system may ground the transmitter antenna at the end of a chip sequence when it is desired to delay transmission of the next chip sequence.
