What is Channel Estimation in Massive MIMO Using BS Identification Code about?

Massive Multi-input Multi-output (MIMO) systems plays an important role in 5G communications. In Massive MIMO, a base station with large antennas simultaneously uses the same frequency and time slots by multiple users, due to this pilot contamination may occur. In order to avoid the pilot contamination in LTE-TDD Massive MIMO systems, a technique is to be considered which uses an orthogonality property of Hadamard code. The pilot signal needs to be modulated with the Hadamard code in order to identify the base station in the cellular network. The identification of base stations can be done by applying the low computational complexity suboptimal linear LS criterion and also the mitigation of the effect of pilot contamination in case of full pilot reuse in multi cell scenarios can also be performed.
