Patent attributes
A new bound on communications capacity, a modulation QLM to derive this bound, and QLM to support communications with performance close to this bound. The QLM modulation and demodulation algorithms offer a method for communications links to support a substantially higher data rate than allowed by the Shannon bound for wired, wireless, optical, and the plurality of communications links. The invention compares QLM modulation performance with phase-shift-keying PSK and quadrature amplitude modulation QAM, describes how it can be used with PSK and QAM, and with gaussian minimum shift keying GMSK, orthogonal frequency division multiple access OFDMA, code division multiple access CDMA, and compares QLM modulation performance with the Shannon bound and the new bound derived in this invention. Additional applications for QLM signal processing and bound include the plurality of information theorectic applications with examples being radar, imaging, and processing.
