frequency-shift keyer造句
例句與造句
- Afsk for audio frequency - shift keying
音頻頻移鍵控 - Fsk for frequency - shift keying
頻移鍵控 - In this paper , bit - error rate performance analyses are presented for coded and un - coded frequency hopping m - ary frequency - shift keyed systems under the condition of additive white gaussian noise ( awgn ) and partial band noise jamming and multitone jamming . the use of error - correct codes provide a way to improve the performance of frequency hopping system , particularly the use of reed - solomon code in a fh system under the condition of partial band noise jamming can greatly improve the performance of system . so we provide the way of coding and decoding of rs code in c language . in the end , we offer the simulation of the performance of time diversity fh / 2fsk system over partial band jamming noise channels
第一章為緒論，敘述跳頻通信的發(fā)展趨勢，以及基本概念，第二章及第三章介紹提高抗部分頻帶干擾的前向糾錯碼reed - solomon碼的原理和實現(xiàn)方法。第四章研究跳頻通信系統(tǒng)在各種干擾條件下的性能。最后在第五章以fh mfsk系統(tǒng)為例，探討在部分頻帶干擾下的系統(tǒng)性能，并進行計算機仿真，仿真結(jié)果表明采用分集技術(shù)和各種編碼技術(shù)對于系統(tǒng)的性能改善具有明顯的效果。 - It's difficult to find frequency-shift keyer in a sentence. 用frequency-shift keyer造句挺難的
