bit-error ratesの例文
- Cvsd （ continuous variable slope delta modulation ） voice coding enables operation at high bit - error rates
- Reducing the bit - error rate in digital communication with error - correction technology and improving the quality of communication have been widely defined and used as the standard technology all over the world
- Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum , which is already extremely scarce . the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level , symbol transmission rate , constellation size , coding rate or any combination of these parameters . thus , without sacrificing bit - error rate ( ber ) , these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions , and reducing throughput as the channel degrades
- 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
