Claim:
1. A system for data transmission comprising: a data stream receive block configured to receive a first data stream, a second data stream, and a third data stream; and a multiplier module configured to multiply, by means of one or more multipliers, the first data stream with a first pseudo-orthogonal waveform, the second data stream with a second pseudo-orthogonal waveform, and the third data stream with a third pseudo-orthogonal waveform for transmission over a carrier using three pseudo-orthogonal waveforms, wherein a first pseudo-orthogonal waveform is cos(θ), the second pseudo-orthogonal waveform is cos(θ+2π/3), and the third pseudo-orthogonal waveform is cos(θ+4π/3), wherein θ=2πft with f being baseband carrier frequency and t being time.
