  • Page 48: Theory Of Operation

    Theory of Operation ¡ µ GSM System Description General Cellular Concept The cellular systems are used to provide radiotelephone service in the frequency range 890-960 MHz. A cellular system provides higher call handling capacity and system availability than would be possible with conventional radiotelephone systems (those which require total system area coverage on every operating channel) by dividing the system coverage area into several adjoining sub-areas or cells.
  • Page 49 BenQ Rev 1.0 ♦ Digital Air Interface - The GSM phone will provide an entirely digital link between the telephone and the base station, which is, in turn, digitally linked into the switching subsystems and on into the PSTN. ♦ISDN Compatibility - ISDN is a digital communications standard that many countries are committed to implementing.
  • Page 50 BenQ Rev 1.0 CELL B CELL E CHANNELS CHANNELS 9-16 9-16 CELL A CELL D CHANNELS CHANNELS CELL C CELL F CHANNELS CHANNELS 17-24 17-24 Figure 2: Hypothetical The radiotelephones themselves are capable of operation on any channel in the system, allowing them to operate in any cell. Due to the low power requirements for communications between radiotelephones in a particular cell and the cell site, operating channels may be repeated in cells which are outside the coverage area of each other.
  • Page 51 BenQ Rev 1.0 calls can share the same carrier. The carrier is divided into a continuous stream of TDMA frames, each frame is split into eight time slots. When a connection is required the system allocates the subscriber a dedicated time slot within each TDMA frame. User data (speech/data) for transmission is digitized and sectioned into blocks.
  • Page 52 BenQ Rev 1.0 Service Area The area within which calls can be placed and received is defined by the system operators. (Because this is a radio system, there is no exact boundary that can be drawn on a map.) If the telephone is outside a coverage area, the (no service) indicator will illuminate and calls will be unable to be placed or received.

  • Page 53: Baseband Function Description

    BenQ Rev 1.0 Baseband function Descriptions ¡ µ 1. Introduction: 56F16 utilizes TI’s chipsets (Ulysse and Nausica) as base-band solution. Base-band is composed with two potions: Logic and Analog/Codec. Ulysse is a GSM digital base-band logic solution included microprocessor, DSP, and peripherals. Nausica is a combination of analog/codec solution and power management which contain base-band codec, voice-band codec, several voltage regulators and SIM level shifter etc.

  • Page 56 BenQ Rev 1.0 3.1.7 Serial Port Interface (SPI) The SPI is a full-duplex serial port configurable from 1 to 32 bits and provides 3 enable signals programmable either as positive or negative edge or level sensitive. This interface is working on 13MHz and is used for the GSM baseband and voice A/D, D/A with Omega.
  • Page 57 BenQ Rev 1.0 3.1.12 TSP Parallel interface (ACT) The parallel interface allows control 13 external individual outputs and 1 internal signal with a time accuracy of the quarter of GSM bit. These parallel signals are mainly used to control the RF activity.
  • Page 58 BenQ Rev 1.0 voltage regulation, battery charging control and switch ON/OFF system analysis. NAUSICA interfaces with the digital base-band device through a set of digital interfaces dedicated to the main functions of Ulysse, a base-band serial port (BSP) and a voice-band serial port (VSP) to communicate with the DSP core (LEAD), a micro-controller serial port to communicate with the micro-controller core and a time serial port (TSP) to communicate with the time processing unit...
  • Page 59 BenQ Rev 1.0 3.2.3 Automatic Power Control (APC) Purpose of the Automatic Power Control (APC) is to generate an envelope signal to control the power ramping up, ramping down and power level of the radio burst. The APC structure is intended to support single slot and multi-slots transmission with smooth power transition when consecutive bursts are transmitted at different power level.

The micro-controller serial port allow read and write access of all internal registers under the arbitration of the internal bus controller. 3.2.7 SIM card shifters (SIMS) To allow the use of both 3V or 5V SIM card types, a SIM level shifter module is included in NAUSICA which interfaces the SIM signal (SRST, SIO, SCLK) at a constant 3V level with Ulysse and 3V or 5V level with the SIM card depending on SIM type.

BFSX is the transmit frame synchronization and is used to initiate the transfer of the transmit data. BDR is the received serial input.
