正方形ABCD的4个顶点各有1人.在某一时刻,4人同时出发以匀速v=10m/s按顺时针方向追逐下一人,如果他们始终保持对准目标,则最终按螺旋状曲线于中心点O.试求出这种情况下每个人的行进轨迹(Four vertices of square ABCD each one. At a time, 4 people starting at a uniform v = 10m/s in a clockwise direction chasing the next person, if they remain at the target, then press the spiral curve in the final Find the center point O. This road track of each person)

A MIMO multiplexing system with NT transmit and NR = NT receive antennas is designed. The main challenge for MIMO systems lies in the non-orthogonality of the transmission channel. This can be solved by turbo processing. Turbo channel encoder is used for converting the bits in its suitable form. Then different M-ary QAM is compared.
