  • Page 15: Overview

    CHAPTER 1 OVERVIEW To achieve a high spectrum efficiency, the i850/i760 digital multi-service, data-capable portable uses a unique modulation technology and sophisticated voice-compression algorithm. The voice of the person speaking into the microphone is converted into a digital bit stream consisting of zeros (0) and ones (1).
  • Page 16 OVERVIEW: iDEN Digital Modulation Technology RL 0dBm 10 dB/ Power (dB) Frequency from Desired Channel Center (kHz) Figure 1-1. Spectrum of iDEN Quad 16QAM Quadrature Phase Shift Keying (QPSK) is one of the most common modulation techniques for satellite communications. In QPSK, a digital data stream is taken two bits at a time to generate four possible phase states of the transmitted carrier.

    OVERVIEW: iDEN Voice Compression Technology (GPS) system. Each burst is numbered; the number is referred to as the slot number. All bursts occurring at a given time carry the same slot number. Inbound transmission bursts (sent from the unit) are offset 19 milliseconds from the outbound burst; the inbound burst begins 4 milliseconds after the end of the outbound burst (see Figure 1-2 on page 1-3).

    It is a PTT (Push-To-Talk)- based feature that operates like most any two-way radio might. A good basic model for operation is that of the Motorola Talkabout product. What makes it quite different, however, is that it is digital in operation, which allows for superior range and voice quality.
