Abstract
The sum-rate performance of multi-cell wireless networks with feedback bits allocation strategy are analysed in this paper. The Doppler power spectrum and autocorrelation function are not appropriate to describe the real wireless channels for which the random environment are time varying. Accordingly the channel is non-constant to describe the Doppler power spectrum and autocorrelation functions. The channel temporal correlation is modelled as a function of delay using the Gauss-Markov model. This paper incorporates the fluctuations in component phases in traditional Clarke's model and studies the effect of number of bits required to quantise the signal plus interference noise ratio. The analysis provides insights on the feedback designs and also shows significant improvement in sum-rate and outage probability.
