What is TD-SCDMA

existing DSP operation speed limit can only do 240km/h; second, the base station coverage radius within 15km, spectrum utilization and system capacity can reach the best, in the user capacity is not very large area, Base station maximum coverage up to 30-4km. Therefore, TD-SCDMA suitable for use in cities and suburbs, both in urban and suburban areas do not affect the actual use of these two deficiencies. Because in cities and suburbs, speed is generally less than 200km/h, urban and suburban po

system, proposing many techniques to meet these requirements: WCDMA, OFDM, TDSCDMA and ODMA. Technical entities of the third generation Partner Project (3GPP) are assigned to analyze these proposed technologies. The result of this work is that WCDMA has become the most preferred technology for 3G systems. 3GPP has written a technical specification, 25.101 of which includes the core performance requirements of the RF hardware part of the WCDMA mobile terminal. 3GPP also defines the two alternati

Differential constraint system

The differential constraint system refers to a series of inequalities:$$ x_j-x_i \le C_{ij} (1\le I, J \le N) $$Of course i,j do not have to take 1-n, and in the case of expansion, for each (I,J), can be a number of $C _{ij}$, but we easily turn them into an inequality.Before solving the inequality group, we can analyze the nature of this inequality group.1.

Application of Operational Research basics: Combinatorial Optimization (4)-Approximate algorithm selection (2)

This lesson proves that the ratio of the first fit algorithm to bin packing problem is 1.7.Averaging volumeIf there are $n $ items, the volume of each item is 0.51, we can analyze the lower bound of the optimal objective function value at least about $n/2$. But the Nether is too loose (in fact the optimal target function value is $n $) and can only be used to prove that the approximate ratio is 2. How can we prove that the ratio is 1.7?The clever mathematicians somehow thought of the method of "

Excellent Agile project Manager is the Sword of project success

If you think about the existing scrum framework, you don't have a role in the project manager (Agile PM). In other agile methods, such as feature-driven development (FDD), people still rely on the project manager (PM). However, the role of the project manager has become more responsible for project administration than for coordinating the development team and its activities or dealing with resource issues (also far from the traditional project manager
