The most straightforward approximation is the standard Gaussian approximation, where the MAI is approximated by a Gaussian random variable. This approximation is simple, however it is not accurate in general. In situations where the number of users is not large, the Gaussian approximation is not app ...
matlab例程 Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular ban
Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communica ...

problem of blind demodulation of multiuser
information symbols in a high-rate code-division multiple-access
(CDMA) network in the presence of both multiple-access interference
(MAI) and intersymbol interference (ISI) is considered.

In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and ...
DSP工具/软件 tas3204
The TAS3204 is a highly-integrated audio system-on-chip (SOC) consisting of a fully-programmable, 48-bit digital audio processor, a 3:1 stereo analog input MUX, four ADCs, four DACs, and other analog functionality. The TAS3204 is programmable with the graphical PurePath Studio™ suite of DS ...
论文 Analysis+of+Device-to-Device+Communications
Device-to-device(D2D) communications are now considered as an integral part of future 5G networks
which will enable direct communication between user equipment (UE) without unnecessary routing via
the network infrastructure. This architecture will result in higher throughputs than conventional cellu ...
书籍 EMI+Protection+for+Communication+Systems
Communication today is not as easy as it was in the past. Protecting numerous com-
munication services, which are operating in the same or adjacent communication
channels, has become increasingly challenging. Communication systems have to be
protected from both natural and manmade interference. Elec ...
