    Third-Generation Systems Design Goals

    ❐ Meet IMT-2000 requirements

    ❐ Offer additional capacity and service enhancements as an

    evolution of 2G systems (TDMA based GSM and IS-95 /

    ANSI-41 based CDMA)

    ❐ Integrated voice and data system

    − Optimized for voice and packet services

    − Support higher rate circuit services

    ❐ Smooth, backwards-compatible evolution from existing

    2G systems

    − Evolve network infrastructure and software from 2G systems − New dual-mode terminals allow gradual build-up of high data rate

    services in 2G service areas

    − Coexistence of 2G voice and data terminals with new wideband

    terminals

    Schemes UWC-136 Proposal

     30 kHz channel -- enhancement to modulation - IS-136+ (64

    kb/s rate)  Wider-band TDMA carriers with channel width 0f 200 kHz

    (IS-136 HS {Vehicular/Outdoor} ) same as EDGE, provides

    medium bit rates 144 kb/s, 384 kb/s

     1.6 MHz carrier (IS-136 HS {indoor}), provides bit rates up to

    2 Mb/s (same as FMA1 without spreading)

     Two new modulation methods

     Quaternary Offset Quadrature Amplitude Modulation

    (QOQAM)  –  higher data rate (2 bits/symbol, symbol is shifted by ππππ/2)

     –  good spectral efficiency

     –  smaller amplitude variation than 16QAM

     Binary Offset QAM (BOQAM)  –  symbol rate 361.1 Ksymbols/s (same as QOQAM)

     –  1 bit/symbol, symbol is shifted by ππππ/2

     –  subset of QOQAM
