A geometry based efficient decoder for underdetermined MIMO systems

“…On the other hand, there are several algorithms featuring fixed complexity or low complexity for underdetermined MIMO systems, such as robust fixed-complexity SDA [15], algorithms for coded MIMO systems [16,17], hybrid approach [18] and heuristic search method [19]. Although [15][16][17][18][19] can achieve lower complexity than [6][7][8][9][10][11][12][13][14] in certain scenarios, they cannot guarantee ML performance.…”

“…Although [15][16][17][18][19] can achieve lower complexity than [6][7][8][9][10][11][12][13][14] in certain scenarios, they cannot guarantee ML performance. Therefore, developing efficient ML decoding algorithm is still an active research field for practical applications.…”
