BER Performance Enhancement of MIMO Systems Using Hybrid Detection Techniques Based on Sphere Decoding	2020	15	.pdf	application/pdf	4173	222	60	Volume 63, No 1, pp 7-21 13 matrix to obtain the modified ̃ and ̃ Afterwards, the lattice reduced channel matrix can be obtained as ̃= ̃ ̃ The same structure can also be used for MMSE detection which takes the noise term into account and thereby leads to an improved performance. Although MMSE detection algorithm reduce the computational complexity, its BER performance is far worse than those of the sphere decoder (SD).	cache/american_scientific_journal-5468.pdf	txt/american_scientific_journal-5468.txt
