Invention: Researchers at the University of Arizona have developed a novel spreading/address code family for high-speed, large-capacity wired/wireless or optical communications. The novel “transposed modified prime codes” (T-MPC) have specific correlation properties and flexible code size, length and weight. This code family is comparable to existing spreading code families in terms of correlations, bit-error rate (BER) performance and cardinality, but. increases the cardinality up to twice that of existing prime code families. Thus, a greater number of users can be accommodated in the system. There is no time-shift feature in T-MPC as in MPC, so the code is not predictable and thus secure.
Background: Multiple access techniques are required to meet the demand for high-speed and large-capacity communications in optical networks in which multiple users are allowed to share the network resources like bandwidth. Optical code-division multiple-access (OCDMA) is attractive due to its potential for enhanced information security, simplified network control, improved spectral efficiency and increased flexility in the granularity of bandwidth that can be provisioned.
* Greater number of users can be accommodated in the system
*Similar to prime codes: employment in a system running prime codes is non-destructive
* Compatible with low-weight prime codes
* Doubles the number of customers that can be carried
* Half the BER
* Time-spreading synchronous code-division multiple-access (CDMA) techniques in electronics and optical communications.
