Reliableness and capability improvement through beam forming using MIMO MC-CDMA system.

Publication Type: Conference

Source(s): AIP Conference Proceedings. 2022, Vol. 2519 Issue 1, p1-6. 6p.

Authors:

Abstract: Co-channel interference corrupts the limit of the Multiple Input Multiple Output Multicarrier Code division multiple access (MIMO MC-CDMA) framework in remote correspondence. Executing beam forming smother the co-channel impedance with the assistance o...

Quadrature Spatial Modulation With the Fourth Order Transmit Diversity and Low-Complexity Sphere Decoding for Large-Scale MIMO Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2022, Vol. 71 Issue 8, p8603-8614. 12p.

Abstract: A quadrature spatial modulation with the fourth order transmit diversity (FO-QSM) scheme is presented in this paper. In this scheme, two dispersion-matrix (DM) sets are assigned at the transmitter, and $P$ out of $Q$ DMs are activated in each set to ex...

Information Rate Optimization for the Non-Regenerative Linear MIMO Relay Channel With a Direct Link and Variable Duty Cycle.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Information Theory. Sep2022, Vol. 68 Issue 9, p5889-5900. 12p.

Abstract: We consider the optimization of a two-hop linear relay channel based on an amplify-and-forward Multiple-Input Multiple-Output (MIMO) relay. The relay is assumed to derive the output signal by applying a Relay Transform Matrix (RTM) applied to the input...

STBC-Assisted MDC-NOMA Image Transmission Scheme for Multi-Antenna Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Broadcasting. Sep2022, Vol. 68 Issue 3, p677-688. 12p.

Abstract: As an efficient and interference-resistant coding technique, multiple description coding (MDC) is proposed with the aim to solve the transmission unreliability problem caused by packet errors, loss or blocking delays. The integration of MDC with non-or...

Diversity analysis of ML and ZF detectors in physical layer network coding relay system over frequency selective channels.

Publication Type: Academic Journal

Source(s): Wireless Networks (10220038). Nov2022, Vol. 28 Issue 8, p3699-3713. 15p.

Abstract: In this paper, we consider a multi-source decode and forward cooperative network coding (NC) relay system based on single-carrier zero-padded (SC-ZP) transmission scheme. All channels are L-tap frequency selective with Rayleigh fading. The cooperative ...

A novel minimal set decode-amplify-forward (MS-DAF) relaying scheme for MIMO-NOMA.

Publication Type: Academic Journal

Source(s): Telecommunication Systems. May2022, Vol. 80 Issue 1, p141-152. 12p.

Abstract: In non-orthogonal multiple access (NOMA) scheme, the strong users, located near to base station, demodulate their data by considering the information of other users as interference. One of the crucial challenges in NOMA is the design of sophisticated i...

Performance analysis of joint dual relay selection and physical layer network coding in two-way relay channels.

Publication Type: Academic Journal

Source(s): Telecommunication Systems. Apr2022, Vol. 79 Issue 4, p529-539. 11p.

Abstract: In this paper, we study joint dual relay- selection (RS) and physical network coding (PNC) schemes for wireless two-way relay channels. We propose four schemes in which the sources transmit information to the relays and two "best" relays are selected b...
