Fast convolution processing has recently been proposed as an efficient means for implementing filter bank multicarrier systems with good spectral containment and high flexibility in tuning the subchannel bandwidths and center frequencies. These features make fast convolution filter banks (FC-FBs) a particularly interesting choice for multicarrier transmission in challenging radio scenarios like...

The combination of Orthogonal Frequency Division Multiplexing and space-time block coding is a promising technique for wireless broadband transmission. In a scenario where other devices generate interference, we propose a scheme where the transmit gains of each OFDM subchannel are adaptively chosen. As a design criteria we consider both the minimization of the interference and maximization of t...

In this paper, we initiate the study of networked stabilization via a MIMO communication scheme between the controller and the plant. Specifically, the communication system is modeled as a MIMO transceiver, which consists of three parts: an encoder, a MIMO channel, and a decoder. In the spirit of MIMO communication, the number of SISO subchannels in the transceiver is often greater than the num...

The resource allocation in SC-FDMA is constrained by the condition that multiple subchannels should be allocated to a single user only if they are adjacent. Therefore, scheduling scheme of D2D-cellular system uses must also conform so-called adjacency constraint. This paper proposes heuristic algorithm with low computational complexity applies proportional fair (PF) system. proposed consists tw...

In this paper, two different dynamic cell coordination stratagies for frequency selective and flat fading are proposed for efficient subcarrier allocation in the joint consideration of adaptive modulation and variable frequency reuse in the channel-aware OFDMA downlink multicellular environment. Compared to a conventional OFDMA system without cell coordination, where system throughput may becom...

By a quantum channel is intended [1, 2] a completely positive and trace-precerving linear map Φ : σ(H) → σ(H), where σ(H) is a set of states in a Hilbert space H with dimH = n ≤ +∞. Even for a finite dimension n < +∞ there is a number of difficult problems concerning the construction of optimal transmission of the information through a quantum channel. The infinite dimensional case we are espec...

To improve the achievable rate for the MIMO channels, we propose a hybrid transmission (HT) scheme that mixes half-duplex decode-and-forward cooperative relaying transmission (DFRH)with direct transmission (DT). In the HT scheme, the source message is divided into two parts: one is transmitted by DFRH scheme and another is transmitted by DT scheme. Precoding and decoding are considered to conve...

The partial overlay of intelligent frequency diversity spread spectrum (FDSS) system on a microwave point to point link is studied. The downlink capacity for the FDSS system is then calculated using a model of 24 cells, and the impact of the FDSS system on the microwave link is investigated. The performance of the microwave point to point link and FDSS users is studied. Results show that the ov...
