Channel Assignment of Cooperative Spectrum Sensing in Multi-Channel Cognitive Radio Networks In this paper, channel assignment for spectrum sensing is studied in multi-channel cognitive radio (CR) networks to maximize the number of channels satisfy... W Wang,B Kasiri,J Cai,... - 《Wireless Comm...
The primary goal of our design is to maximize the number of feasible concurrent CR transmissions with respect to both spectrum assignment and transmission power. Energy conservation is also treated, but as a secondary objective. The problem is posed as a utility maximization problem subject to ...
An integrated omnichannel strategy serves as the foundation for success in the modern marketing world. This guide takes a deep dive into the complexities of crafting an effective Connected TV (CTV) strategy, showcasing its pivotal role within the overarc
The aim is to assign channels to stations so that the interference is controlled within an acceptable level and the spectrum of channels used is minimized. This channel assignment problem can be modeled as the multiple t-separated $$L(j_1,j_2,\ldots ,j_m)$$ L ( j 1 , j 2 , …...
Tb/s superchannels have also led to a rethinking of spectral bandwidth allocation beyond the current fixed grid architectures, leading to the so-called flexible grid architecture that allows for more efficient utilization of the optical spectrum. In this chapter, we review recent progress on Tb/s...
That is, each second of time on the channel is divided into a number of intervals called bit times, the number being equal to the channel capacity. For example, in a 1-Mbps channel, a bit time is 1 μs long. Each bit time may be occupied by an information or data bit, or it ...

depending on the system. For example, a maximum BER of 10−12or 10−9was often considered to be required for systems in the late 1980s or 1990s. This threshold can be relaxed using a family of signal coding techniques known asforward error correction(FEC), in which a number of data...
