| Software Radio have get remarkable development since firstly introduced by Jeo Mitola in 1992. It has several new characteristic:opening hardware platform,using updateable and reconfigurable application software to realize all kinds of radio function. This type of software radio is expected to be a key technology in several application fields of wireless communications,including cellular telephony,military communications,micro-electronics and etc.The Software Radio Gateway is application of Software Radio technology in military communication. Based on this Gateway,a 16kbps FH-GMSK wireless data transmission have accomplished.The arrangement of the thesis is below:Chapter 1 gives brief description of software radio in the origin and development status and for the futureChapter 2 introduces the theory related to software radioChapter 3 introduces the characteristic about wireless channel and some estimation way of channelChapter 4 introduces scheme of wireless data transmission. A 16kbps FH-GMSK wireless data transmission have accomplished,the mainly modem algorithm is done by DSPChapter 5 summary... |
