This is possible with the help of expanded constellation; also it enables the destination to combine the received signals in the broadcast phase and the relay phase. Later the performance of the SSC scheme is analysed and numerical results are obtained, with the help of that result two design criteria are derived so that it can achieve the maximum performance from the system. Spatial diversity techniques are used in order to increase system reliability; also it won’t affect the bandwidth or performance. We use cooperative diversity as alternative to achieve special diversity, where antenna diversity become impractical due to size and power limitation of mobile devices. The concept of cooperation among users to provide diversity was introduced by Sendonaris, and then Laneman (Motahari, Ahmadzadeh & Khandani) derived the formulation for cooperative diversity based on two cooperative schemes, namely Amplify and Forward (AF), and Decode and Forward (DF). Signal space diversity was introduced by Belfiore and Boulle (Motahari, Ahmadzadeh & Khandani), which is achieved with the modulation signal space. Here we spread information carried by each signal point across all components of that particular signal point. And then send each component through an independent channel. The performance of the cooperative schemes, which uses the signal space diversity, is affected by the performance of the source-relay channel. Meanwhile, a method called Signal Space Cooperative (SSC) scheme has been proposed to overcome this problem however, which is not easy to scale larger constellations. And also here we take an assumption, that the destination is aware of whether the relay participates in the cooperative scheme or not. Signal Space Cooperative Scheme SSC scheme is the major proposal by this paper. To demonstrate SSC scheme, first we have to see the Constellation Expansion Algorithm that enables the relay to effectively cooperate during the course of transmission. Then, the broadcast phase and the relay phase signals are described followed by a discussion on how the destination decodes received signals. Constellation Expansion In order to achieve maximum diversity gain, any two signal points in the system constellation must have the maximum number of distinct components. Let us consider

Signal Space Cooperative Communication This paper proposes a new idea called ‘Signal Space Communication (SSC)’ which is based on the concept of signal space diversity. In Signal Space Communication, there should be cooperation between the source and the relay and here the cooperation is achieved with the help of ‘Novel Constellation Design’ (Motahari, Ahmadzadeh & Khandani)…

The Different Types of Underwater Communication Diver Underwater Communications One of the most common uses of underwater communication technologies is for the divers. There are types of underwater communication gadgets used by the divers. These include the tools used to communicate to the surface and the tools used to communicate with another diver.
Individuals use the non-verbal communication in every mode of interaction. It conveys a message that is different from the verbal communication; hence, a person must be particular with interpreting body language because the truth lies in it. Through non-verbal communication, receiver can easily detect the message underlying the word’s meaning.
Cooperatives are organized for many reasons, including providing services that private investor-owned company may not find profitable enough, providing a measure of competition and reducing purchasing costs through volume buying. Co-ops are owned by consumers, producers, farmers, workers, businesses, organizations, municipal and government.
Strategic network seeks to develop a competitive advantage in primary or support activities. A strategic center firm often manages the network. SCN engages in four types of tasks: Strategic outsourcing, Competencies, Technology, and Race to learn.
In this manner, this literature review exemplifies the most essential aspects of cooperative learning.
Cooperative learning is hailed as a successful teaching strategy wherein small teams, which are having students of different levels of ability, use a variety of learning activities to improve their understanding of a subject.
In the short-term (1 to 3 years from now), I want to pursue a Masters Degree in Engineering in a U.S. university, specifically in the field of signal processing and communication, that will open the door for me to achieve my medium- and long-term objectives.
To initiate their actions, they bind to a specific receptor on the plasma membrane.
Insulin is the major protein hormone produced and secreted in the pancreas. Its main functions are to regulate the production of storage
As a result, they form a set space. A gang set space can be referred to as the actual region where members of a gang come together as a gang, within a particular neighborhood (Tita, Cohen, and Engberg 273). The aim of this paper is to demonstrate gang
