Receiver Design for LTE
The main objective of the study is to take action for the entire measurement receiver. However, many factors can affect the performance of the receiver, such sub-blocks of receipt must be checked on the basis of the first and measurable contributions eliminate or reduce uncertainty.
If using multiple receivers, it is necessary to make these measurements based on each separate receive chain before verifying the effectiveness of MIMO. Principles discussed here apply to both frequency division duplex (FDD) mode and time division duplex (TDD) access FDD. Although there are examples of a typical block diagram of a mobile radio telephone LTE is shown in Figure.
Modern receivers use the same blocks as classical models; However, today there is a higher degree of integration with unique components performing multiple functions, especially in the mobile space is at a premium (which means it will probably be fewer places where signals may be injected or observed test ).
Here we focus on a subset of receiver design and testing considerations, in particular: Open and closed loop operation, wide bandwidth, signal analysis of several areas affecting the channel, and finally pre-coding and code list LTE.
