The Large Intelligent Antenna System (LIS) is a noteworthy development in wireless communications by targeted propagation waves. The LIS idea goes beyond massive MIMO. The LIS consists of a surface that radiates continuously and is made up of a number of small panels that are placed close to the users and can exchange signals. This paper shows the results of a combination of LIS systems with Low-Density Parity-Check (LDPC), comprising Single Carrier with Frequency Domain Equalization (SC-FDE) with four different receiver types: Equal Gain Combining (EGC), Maximum Ratio Combining (MRC), Zero Forcing (ZF), and Minimum Mean Squared Error (MMSE). It is shown that, in the above-described scenario, for some receiver types, equalization can be avoided without degrading performance, while the complexity is reduced.
