SVD-Based Receiver for Downlink MIMO MC-CDMA Systems
In this paper, a new receiver for downlink multicarrier code-division multiple-access (MC-CDMA) system is proposed when the channel between the transmitter and each user is multiple-input multiple-output (MIMO). The structure of the proposed...
پرتوسازی در سیستم های چندکاربره MIMO MC-CDMA با استفاده از SVD گروهی
در این مقاله ساختار جدیدی برای پرتوسازی در سیستم های MIMO MC-CDMA چندکاربره در حالت فروسو ارائه شده است که عملکرد بهتری در برابر دو عامل تداخل چندکاربره (MUI) و تداخل هم کانال (ICI) دارد. در این ساختار برای حذف ICI از پرتوسازی مشترک در فرستنده و...
Novel spreading codes for multicarrier code division multiple access based cognitive radio networks with sidelobe suppression
The deployment of multicarrier code division multiple access as the transmission scheme of the spectrum overlay based cognitive radio (CR) networks faces two challenging issues: (i) the need for spreading codes with arbitrary ...
A novel multicarrier CDMA transmission scheme for cognitive radios with sidelobe suppression
Noncontiguous multicarrier code division multiple access (MC-CDMA) is an effective multiple access
method for cognitive radio systems that can deploy the noncontiguous vacant parts of a certain spectrum
shared with the users of a...
Joint Transceiver Design for Uplink MIMO MC-CDMA Systems
Multiuser interference (MUI) and multiple-antenna
interference (MAI) are two challenging issues in design of
multicarrier code-division multiple-access (MC-CDMA) systems
for communication through multiple-input multiple...
Receiver Design for Downlink MIMO MC-CDMA in Cognitive Radio Systems
Multiuser interference (MUI) and co-space
interference (CSI) are two challenging issues in design of
multicarrier code-division multiple-access (MC-CDMA) systems
when multiple antennas are used at both the transmitter and...
