  • Modulation method and system using constant envelope ODSCDMA with low out-of-band emissions for non-linear amplification
    Patent number: 5903555
    Abstract: A method and an apparatus are provided for transmission of band limited QPSK data which is orthogonal direct-sequence spread using a BPSK sequence which preserves the band limiting even with subsequent amplification by non-linear amplifiers. This feature allows inexpensive implementation in mass produced, portable communications devices.
