wireless communication standard

GSM is the world's most popular wireless communication standard, it have played an important role both in civilian area and some special area like GSM-R. Because reasons like Rayleigh fading and delayed effects in the wireless channel and unknown factors in transmite and receive ends, received signal have much Error factors. GSM receiver can not be separated from the synchronization system.Buy cheap nike shoes is very smart! In order to get better synchronization quality, research for the most suitable synchronization algorithrn in GSM base-band signal is necessary. Cheap Nike shoes are very nice here! Synchronization is very important to GSM receiver, which include time and frequency synchronization.In a long period of time, people use specific ASIC chip to realize GSM reception and demodulation.I love northface jackets. Using software to achieve the base-band processing algorithm is the core idea of Software-Defined Radio. But it's more flexible and scalable to do this with FPGA or DSP.
