A CDM (synchronous CDMA), TDMA, or FDMA receiver can in theory completely reject arbitrarily strong signals using different codes, time slots or frequency channels due to the orthogonality of these systems.
Because of the orthogonality property of the carrier signals, it is possible to detect the modulating signals independently.
Implementation using the FFT algorithm The orthogonality allows for efficient modulator and demodulator implementation using the FFT algorithm on the receiver side, and inverse FFT on the sender side.
Here, the projections are accomplished by the orthogonality of the solenoidal and irrotational function spaces.
Such properties include the completeness, orthogonality, Plancherel/Parseval, periodicity, shift, convolution, and unitarity properties above, as well as many FFT algorithms.
Synchronous CDMA exploits mathematical properties of orthogonality between vectors representing the data strings.
