Today's world is demanding high data volume communication without any major interruption in the channel. To fulfill the user's requirements Multiple Input Multiple Output (MIMO) technology seems promising which enhance the capacity of the channel. A channel is a medium through which signal travels. MIMO sends data on multiple paths using multiple antennas. At up-link receiver end of the MIMO system, to restore data special algorithms are used. Space and Time complexity of those algorithms play an important role in these systems to increase the performance. Time Complexity plays an important role when both variations give the same Bit Error Rate (BER). This paper will discuss the Time and Space complexity of Differential Evolutionary (DE) based CE-UD MIMO system with Channel Estimation and User Detection. These analyses are verified mathematically as well as on simulations using MatLab 2017.
