1. A carrier interferometry (CI) transmitter, comprising: a CI coder adapted to encode at least one data sequence onto a CI code to produce at least one data-bearing code vector and to adjust subcarrier weights, and a modulator adapted to modulate the at least one data-bearing code vector onto a plurality of subcarriers, wherein at least one of the modulator or the CI coder is adapted to scramble CI codes generated by the CI coder.
