In most of the cases when I wanna express myself in English I just had weird feeling. It seems that I am looking for a unfamiliar feeling. Anyway, from now on I should write more in English.
In the past few weeks I started my undergraduate thesis. it's about Space-Time Coding for MIMO wireless communication. This topic requires truly comprehensive knowledge about both complex random process and digital communication, on which I have little backgroud. Also I have found that my mathematic backgroud is not as solid as I expected before. i.e., I even forgot that the product of all nonzero eigenvalues is the determinant of the matrix-__-#. I don't know how to describe the wireless communication channel and signals. I don't know what does the constellation of n-PSK or n-QAM means...
Take a retrospect of my past half and three years of learning in EE of SJTU, I am shocked by the fact that I barely konw what I have learned and what am I gonna to do. I have learned miscellaneous stuffs but am not good at any specific field.
Everything will be fine~
