  • Simulation of BCCH Channel of GSM/PCN Base Station with Signal Generator SME

    Propagation measurements are indispensable in the planning of digital, cellular mobile radio net-works. To find the optimum sites for the base stations, a mobile test transmitter system simulating the base station is operated from a number of possible locations. The test receiver system is accommodated in a vehicle, which is driven along a test route to perform measurements. The parameters measured, such as level, bit error rate or channel impulse response, provide information on the coverage within the cell. The main problem is to minimize interference caused by multipath propagation in the reception area. The SME offered by Rohde & Schwarz is a universal test generator that can be used as the core of a test transmitter system. The SME generates the GMSK-modulated signals required for GSM propagation measurements in line with the rele-vant standards. Thanks to its low weight of 17 kg it can be carried even to remote sites. Fitted with the new optional DM Memory Extension (SME-B12, in the following referred to as XMEM), the SME is able to store data sequences of up to 8 Mbit which are long enough for receiver measurements with test mobile stations. A suitable test receiver system is for instance a test mobile station for measuring level and bit error rate and the Impulse Response Analyzer PCS from Rohde & Schwarz for measuring the channel impulse response. The present Application Note describes how the XMEM can be loaded with suitable data (test sequence) by the GSM Radiocommunication Test Set CRTP from Rohde & Schwarz and how the SME has to be adjusted for GMSK modulation of these data. First, however, an overview is given of all functions of the XMEM and their operation supplementary to the Operating Manual. Finally, it is explained how the XMEM data can be transferred between PC and SME via the IEEE-488 or RS-232 interface.

  • Generation of Test Signals for IS-136 (NADC) with Signal Generator SME

    Communication systems according to IS-136 (NADC) use Time Division Multiplex Access (TDMA) for the communication between base station and mobile stations. There are 6 time slots available. Depending on the amount of data, which have to be transmitted, the system uses full rate channels or half rate channels. A full rate channel means, that the mobile is accessed every 3rd time slot (e.g time slot 1 and 3, time slot 2 and 4 or time slot 3 and 6). With half rate channels the mobile is accessed every 6th time slot. Full rate and half rate channels may be mixed on demand. The base stations transmit continous on their frequency. Depending on the used combination of full rate and half rate channels the base station uses a different sequence of synchronisation words. The mobile stations use bursted transmission with one of the synchronisation words S1 to S6 defined in the standard. Signal Generator SME is excellently suited to generate these signals to test either base station receivers or mobile phone receivers. Together with the modulation data supplied with this application note the SME serves as a signal source for various test and measurement applications in the whole frequency range of IS-136 (NADC).
