In Fixed Channel Allocation or Fixed Channel Assignment (FCA) each cell is given a predetermined set of frequency channels. FCA requires manual frequency planning, which is an arduous task in time-division multiple access (TDMA) and frequency-division multiple access (FDMA) based systems since such systems are highly sensitive to co-channel interference from nearby cells that are reusing the ...
Dynamic Frequency Selection (DFS) is a channel allocation scheme specified for wireless LANs, commonly known as Wi-Fi. It is designed to prevent electromagnetic interference by avoiding co-channel operation with systems that predated Wi-Fi, such as military radar , satellite communication , and weather radar , and also to provide on aggregate a ...
Dynamic RRM schemes adaptively adjust the radio network parameters to the traffic load, user positions, user mobility, quality of service requirements, base station density, etc. Dynamic RRM schemes are considered in the design of wireless systems, in view to minimize expensive manual cell planning and achieve "tighter" frequency reuse patterns, resulting in improved system spectral efficiency.
Go beyond cookie-cutter strategies Traditional asset allocation models that point you to fixed percentages are useful benchmarks, but you shouldn't just follow them blindly. Instead, adjust those ...
An allocation that is both MBB and e-pEF1 is also e-EF1. [9]: Lem.4.1 Least-spender: Given an allocation and a price-vector, it is the agent i such that p(X i) is smallest (ties are broken based on some prespecified ordering of the agents). Note that an allocation is e-pEF1 iff the e-pEF1 condition is satisfied for the least spender (as agent i).

We watch movies for so many reasons: the spectacle of great cinematography, the experience of connecting with a director's ideas, the sheer pleasure of watching a story unfold before us. But we ...
The pros and cons of DCA have long been a subject for debate among both commercial and academic specialists in investment strategies. [11] It is easily demonstrated mathematically that dollar cost averaging (as defined by Benjamin Graham) is superior to the alternatives of purchasing a fixed number of shares with the same time intervals.
