Capacity and Optimal Power Allocation of Poisson Optical Communication Channels
نویسنده
چکیده
in this paper, the channel capacity for different models of Poisson optical communication channels has been derived. The closed form expression for the single input single output (SISO) Poisson channel -derived by Kabanov in 1978, and Davis in 1980will be investigated. In addition, we derive closed form expressions for the capacity of the parallel Poisson channel and the capacity of the multiple access Poisson Channel (MAC). The optimum power allocation is also derived for different models; results have been analyzed in the context of information theory and optical communications.

متن کاملAsymptotic Close to Optimal Resource Allocation in Centralized Multi-band Wireless Networks
This paper concerns sub-channel allocation in multi-user wireless networks with a view to increasing the network throughput. It is assumed there are some sub-channels to be equally divided among active links, such that the total sum rate increases, where it is assumed each link is subject to a maximum transmit power constraint. This problem is found to be a non-convex optimization problem and i...
متن کاملJointly power and bandwidth allocation for a heterogeneous satellite network
Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
