Research And Implementation Of DSP Downlink Baseband Module Of GSM Terminal Test Set

Recently, the technology of TD-SCDMA is developed fastly, the emergence of the new technology and new application requests instrument manufacturers to follow up quickly, and introduce corresponding solutions. Under the environment of gradual matured TD-SCDMA industry, terminal test enterprises have large stress, and how to make domestic test equipment accepted by consumers is a big challenge to domestic test equipment manufactures.Till now, the number of 2G terminal user is close to 757 million, and so the coexistence of 2G and 3G networks is inevitable, dual-mode or multi-mode handset market will be the inevitable choice for the transition phase. Dual-mode and multi-mode mobile phone can effectively reduce the cost of operators; protect the operator's existing customer resource. Promote the smooth transition from 2G to 3G In order to meet the needs of the market for 2G and 3G multi-mode test instrument, "GSM/GPRS/EDGE test set" project was launched.This dissertation mainly focuses on research and development work in "GSM/GPRS/EDGE Test Set".The main contents of the dissertation list as follows:1, Technical standard of the 2G mobile telecommunication system GSM and its enhanced edition GPRS/EDGE; and an introduction of my main work during the post-graduate.2, The development environment TI TMS320C6000 DSP; the development tool CCS 2, GSM system structure.3, The general framework of design ideas in test set, which includes hardware platform and software architecture.4, The interface of physical layer with layer 2, layer 3, main controller and measurement.5, Physical layer's internal data process, which includes each kind of physical channel's function, channel coding and decoding, and the related functions...
