Performance evaluation of different frequency reuse patterns and channel coding schemes in GPRS
Peter Larsson, Hans Olofsson · 2002
In the Global System for Mobile Communications (GSM) phase 2+ development, one major activity has been to specify the General Packet Radio Service (GPRS). The purpose of GPRS is to accomplish efficient dynamic spectrum resource sharing between data sources that are bursty in nature, GPRS is well integrated in the overall GSM structure, to allow smooth introduction in existing GSM networks. Four channel coding schemes are defined for GPRS, which facilitates high throughput in a variety of radio conditions. The spectral efficiency of these schemes is analyzed in a cellular system with different omnicell frequency reuse patterns (1, 3 and 7). The results show that a frequency reuse of 3 and a code rate of 2/3-3/4 is the most spectrum efficient combination.
