Researching And Realization Of Physical Layer Technology Of GSM Mobile Equipment

In this article, I explored and researched arithmetic and realization of key technology in physical layer of GSM mobile phone at pre-researching level. The technology of this part is composed by four parts: speech encoding and decoding, channel encoding and decoding, Viterbi equilibrium and decoding, SIM card driving. They are described by C language and Verilog hardware describing language, and realized by software and hardware emulating.
