Comment on 'Statistical mechanics of CDMA multiuser demodulation'
arXiv:cond-mat/0111003 · doi:10.1209/epl/i2002-00576-1
Abstract
In a recent paper, Tanaka formulated and solved a model of CDMA multiuser demodulation by applying the theory of spin glasses, the replica method in particular. It is shown in the present comment that some of his results can be derived without recourse to the replica method; conclusions from the somewhat tricky replica method are justified rigorously.
