AC vs DC: Direct current flows in one direction and is used in applications requiring stable voltage, while alternating current can reverse direction and is typically used where varying power levels are needed. DC Current Symbol: The symbol for DC current is a straight line, indicative of its ...
Finally, the prior symbol estimate can be obtained from (6.46)λa(sˆ)=-∑j=1lcjLD,e(cj), where (6.47)LD,e(cˆj)=Lcj(t)-Lcj(t-1). In Eq. (6.47), we use L(cj(t)) to denote the LDPC decoder output in current iteration (iteration t). The bit LLRs L(cj) are determ...
where m is the number of different sequences for each source symbol and h = H(Y | X), a constant independent of the input distribution when the channel noise is symmetric. This is the case for expression (9.12), when each row of the matrix has the same probabilities except in different...
Direct current abbreviated as DC or dc, is an electric current in which electrons always flow in the same direction. The circuit symbol of a DC source and DC voltmeter is as shown – DC generators, fuel cells, solar cells, and electric cells are sources of unidirectional current. This is ...

When GPU memory is allocated as writecombined, the userspace mapping should also be done as writecombined by passing the vm_page_prot member of vm_area_struct to the standard linux interface: `pgprot_writecombine() <https://elixir.bootlin.com/linux/latest/source/arch/arm64/include/asm/pgtabl...
In our analytical framework, the ‘+’ symbol is strategically used to represent the expected positive effect of various independent variables—including e-commerce, foreign direct investment, labor resource endowment, technological investment, knowledge capital, and education level—on the export volumes ...
