In this paper we consider a multiple access system with oversaturation of the channel by means of a combined OCDMA/OCDMA scheme with scrambled orthogonal bases. We investigate the performance and the associated maximum channel capacity (channel load) for uncoded BPSK modulation with binary valued chip sequences and optimum multiuser detection for spreading factor N = 4, 8, 16 and 32. It is foun...
Introduction: Loss of inhibitory output from Purkinje cells leads to hyperexcitability of the Deep Cerebellar Nuclei (DCN), which results in cerebellar ataxia. Also, inhibition of small-conductancecalcium-activated potassium (SK) channel increases firing rate f DCN, which could cause cerebellar ataxia. Therefore, SK channel activators can be effective in reducing the symptoms of this disease, ...
A general capacity formula C = sup X I(X; Y), which is correct for arbitrary single-user channels without feedback, is introduced in this tutorial. This new capacity formula is obtained by using a general channel model without any assumptions of the channel, introducing the notion of inf/sup-information/entropy rates, and finding a new tight converse bound on the error probability. In Section 1...
