The need for higher data rate and higher s.s.ems.capacity leads.to s.veral s.lutions.including higher cons.ellation s.ze, s.atial multiplexing, adaptive modulation and Non-Orthogonal Multiple Acces. (NOMA). Adaptive Modulation makes.us. of the us.r’s.location from his.bas. s.ation, s.ch that, clos.r us.rs.get bigger cons.ellation s.ze and hence higher data rate. A s.milar idea of adaptive modulation that makes.us. of the us.r’s.locations.is.the NOMA technique. Here the bas. s.ation trans.its.compos.te s.gnals.each for a different us.r at a different dis.ance from the bas. s.ation. The trans.itted s.gnal is.formed by s.mming different us.r’s.cons.ellations.with different weights. The clos.r the us.rs.the les. average power cons.ellation is.us.d. This.will allow the clos.r us.r to the bas. s.ation to dis.inguis. his.cons.ellation and others.cons.ellation. The far us.r will only dis.inguis. his.cons.ellation and other us.r’s.data will appear as.a s.all interference added to his.s.gnal. In this.paper, it is.s.own that the Adaptive modulation and the NOMA are s.ecial cas.s.of the more general Clus.er Modulation technique. Therefore, a general frame can be s.t to des.gn both modulation s.hemes.and better unders.anding is.achieved. This.leads.to des.gning a multi-level NOMA and/or flexible adaptive modulation with combined channel coding.
