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 program analysis is the act of analyzing software that involves executing a program – as opposed to static program analysis, which does not execute it.. Analysis can focus on different aspects of the software including but not limited to: behavior, test coverage, performance and security.
The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.
Examples of dynamic RRM schemes are: Power control algorithms; Precoding algorithms; Link adaptation algorithms; Dynamic Channel Allocation (DCA) or Dynamic Frequency Selection (DFS) algorithms, allowing "cell breathing" Traffic adaptive handover criteria, allowing "cell breathing" Re-use partitioning; Adaptive filtering
In computer science, region-based memory management is a type of memory management in which each allocated object is assigned to a region.A region, also called a zone, arena, area, or memory context, is a collection of allocated objects that can be efficiently reallocated or deallocated all at once.
Type sensitivity is a variant of object sensitivity where the allocation site of the receiver object is replaced by the class/type containing the method containing the allocation site of the receiver object. [13] This results in strictly fewer contexts than would be used in an object-sensitive analysis, which generally means better performance.
In computer science, manual memory management refers to the usage of manual instructions by the programmer to identify and deallocate unused objects, or garbage.Up until the mid-1990s, the majority of programming languages used in industry supported manual memory management, though garbage collection has existed since 1959, when it was introduced with Lisp.
Dynamic memory allocation can, and has been achieved through the use of techniques such as malloc and C++'s operator new; although established and reliable implementations, these suffer from fragmentation because of variable block sizes, it is not recommendable to use them in a real time system due to performance.
