For classical MIMO detection, I recommend the paper "MIMO Detection Methods: How They Work" (https://www.diva-portal.org/smash/get/diva2:242286/FULLTEXT01.pdf)

For Massive MIMO, I recommend Chapter 4 in my book that you can download here: http://massivemimobook.com

Following are the main detection techniques proposed for MIMO

1) Linear Detectors Based on the Approximate Matrix Inversion

2) Detectors Based on Local Search

3) Detectors Based on Belief Propagation

4) BOX Detection

5) Sparsity Based Algorithms

6) Machine Learning for Massive MIMO Detection

Each detection techniques have several subtechniques. You can refer to the following work for more details

I recommend the paper ''A Primer on MIMO Detection Algorithms for 5G Communication Network'' Article A Primer on MIMO Detection Algorithms for 5G Communication Network
