- Abstract
- A novel modulation scheme suitable for noncoherent demodulation based on quaternary quasi-orthogonal sequences is. proposed. Compared to orthogonal modulation, the controlled quasi-orthogonality between the sequences allow significantly increased bandwidth efficiency with little or no degradation in power efficiency. A hardware efficient demodulator structure using fast Walsh transforms is also presented.
