Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes … See more The link spectral efficiency of a digital communication system is measured in bit/s/Hz, or, less frequently but unambiguously, in (bit/s)/Hz. It is the net bit rate (useful information rate excluding error-correcting codes See more In digital wireless networks, the system spectral efficiency or area spectral efficiency is typically measured in (bit/s)/Hz per unit … See more • Baud • CDMA spectral efficiency • Channel capacity • Comparison of mobile phone standards See more Web开馆时间:周一至周日7:00-22:30 周五 7:00-12:00; 我的图书馆

WebGSM also provides a spectrum efficiency of about 4% (8 × 13 Kbit/s/200 kHz × 1/12 reuse). IS-95 CDMA provides a spectrum efficiency of 4–7% (12 to 20 × 8 Kbit/s/1250 kHz × 1 reuse × 1/2 voice activity). Dynamic channel assignment combined with circuit-based technology (which has generally been the approach taken to date) can provide some ... WebA wireless communication system should use the spectrum in an efficient manner. The system spectral efficiency can be defined as. (16.14) in which R is the bit rate, B is the bandwidth, and K is the cluster size. The fraction R/B can be considered as the link spectral efficiency and is linked to the Shannon formula (Equation (16.1)). some splainin to do
