A PROPOSED MODEL OF MIMO CHANNEL IN REALISTIC ENVIRONMENT

3.1.1 Environment and measurement procedures
To capture the propagation characteristics of the typical UMi scenario, the measurement site and scenarios are selected in downtown area of Beijing, China. The bird ’ s eye view of the measurement environment is[r]

Two compromising principles for QoS provisioning in the MANETs are: soft QoS and QoS adaptations.Soft QoS means that after the connection setup, there may exist transient periods of time when the QoS specification is not honored. However, we can quantify the level of QoS satisf[r]

The paper also uses power allocation for these beams on principle of “ water filling”, the gain of path is better, more transmit power is assigned to the path. The simulation can show the SER is improved if using more beams for more paths and also the optimal power allocation is giving the lower SER[r]

Our proposed low-complexity interference-aware receiver structure not only reduces one complex dimen- sion of the system but is also characterized by exploiting the interference structure in the detection process. Con- sidering this receiver structure, we investigate the effec-[r]

the ( N − 1) links with their corresponding inter-vehicle distance values. If all the links in a snap shot are connected, the network is considered to be connected. The connectivity distance is then evaluated as the length of connected path from a vehicle. The connectiv[r]

The first remark is that the system allows residual bit er- rors in the transmitted substreams. This means that all sub- streams are e ff ectively used by the source decoder, with a possibility to qua[r]

The design constraint in (16) obtains the optimal channel quality, but the large antenna spacing is difficult to achieve in practice. However, practically, the condition number around 10 is allowed from the view of link quality. For example, if c[r]

In this paper, we develop a mathematical model for PRVs capable of describing complete operation modes of PRVs in practice. In addition, we show that the PRV model equation can be relaxed so that it is useful for formulation of NLP. With the proposed PRV model, the formulated NLP can be solved by NL[r]

This paper presents a heuristic method to minimize makespan for different jobs in a job shop scheduling. The proposed model is based on a constructive procedure to obtain good quality schedules, very quickly. The performance of the proposed model of this paper is examined on standard benchmarks from[r]

2. MATHEMATICAL BACKGROUND
2.1. Hammerstein model
The Hammerstein model consists of a static nonlinearity fol- lowed by a linear time-invariant system as defined in [ 24 ] and presented in Figure 1 . The Hammerstein model can be viewed as a[r]

approaches where SUs are modeled as the players of a game. In this context, they make decisions in their own self interest by maximizing their utility function, while influenced by the other players decisions. Generally, the di ff erent control- lable transmission parame[r]

We then apply our supertagger to NP chunking. The purpose of this paper is to find a better way to exploit syntactic information which is useful in NP chunking, but not the machine learning part. So we just use TBL, a well-known algorithm in
