Simulation of a transmitter implementing the OFDM transmission chain with QPSK modulation on each sub-carrier
通讯编程文档 A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM)
A MATLAB program has been written to investigate Orthogonal Frequency Division
Multiplexing (OFDM) communication systems. This program is valuable for future researchers
simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier
OFDM are compared to demonst ...
书籍 Bandwidth-Efficient+Digital+Modulation
Traditional modulation methods adopted by space agencies for transmit-
ting telecommand and telemetry data have incorporated subcarriers as a sim-
ple means of separating different data types as well ensuring no overlap
between the radio frequency (RF) carrier and the modulated data’s frequency
spe ...
书籍 LTE-Advanced+Relay+Technology
LTE-Advanced becomes a truly global standard for 4G cellular communications.
Relay, as one of the key technologies of LTE-Advanced, can significantly extend
the coverage, and improve the system throughput. LTE-A standards and tech-
nologies were described in several recent books where the limited pa ...
书籍 OFDM+Wireless+LANS
Before delving into the details of orthogonal frequency division multiplexing (OFDM), relevant
background material must be presented first. The purpose of this chapter is to provide the necessary
building blocks for the development of OFDM principles. Included in this chapter are reviews of stochast ...
书籍 qorvo-carrier-aggregation-fundamentals
Mobile operators must continuously pursue cost‐
effective and efficient solutions to meet the high data
demand requirements of their subscribers. Limited spectrum
allocations and non‐contiguous spectrum blocks continue
to pose challenges for mobile operators supporting large
data uploads and downl ...
书籍 SC-FDMA+for+Mobile+Communications
The single-carrier frequency division multiple access (SC-FDMA)
system is a well-known system that has recently become a preferred
choice for mobile uplink channels. This is attributed to its advantages
such as the low peak-to-average power ratio (PAPR) and the use of
frequency domain equalizers. Lo ...
书籍 Software+Radio
Software Radio (SR) is one of the most important emerging technologies for the
future of wireless communication services. By moving radio functionality into
software, it promises to give flexible radio systems that are multi-service, multi-
standard, multi-band, reconfigurable and reprogrammable by ...
书籍 ESD Protection in CMOS ICs
在互補式金氧半(CMOS)積體電路中，隨著量產製程的演進，元件的尺寸已縮減到深次微
米(deep-submicron)階段，以增進積體電路(IC)的性能及運算速度，以及降低每顆晶片的製造
成本。但隨著元件尺寸的縮減，卻出現一些可靠度的問題。
在次微米技術中，為了克服所謂熱載子(Hot-Carrier)問題而發展出 LDD(Lightly-Doped Drain)
製 ...
