Focusing　on　the　high　computational　complexity　of　cooperative　selection　methods　in　LTE　uplink　channels,　an　improved　user　selection　method　is　proposed　in　this　paper.　The　selection　method　is　based　on　the　channel　quality　and　signal-to-noise　(SNR)　of　cooperative　user.　This　method　is　mainly　divided　into　the　following　two　steps:　firstly,　the　user　with　poor　quality　channel　condition　selects　a　user　with　better　channel　condition　as　its　candidate　cooperative　user;　secondly,　the　method　needs　to　consider　the　channel　environment　between　the　candidate　cooperative　user　and　the　base　station.　Thus,　the　cooperative　user　could　be　selected　after　those　two　steps.　Simulation　results　show　that　the　cooperative　user　selection　method　can　not　only　reduce　the　bit　error　rate　(BER),　but　also　improve　the　capacity　of　the　system.　Moreover,　the　proposed　method　has　not　much　effect　on　the　success　rate　of　the　cooperative　user　selection　process.　So　the　transmission　efficiency　can　be　improved　and　the　system　performance　can　be　optimized.　©　2013　IEEE.
