Abstract

In this paper we derive asymptotic performance measures for peer-to-peer multi-carrier CDMA networks with low data rate feedback channels between transmitter-receiver pairs. We derive expressions for the asymptotic average signal to interference and noise ratio at the output of the optimal linear multi-signature receiver using a simple feedback scheme in the single-user case, and an approximate expression in the two-user case. The asymptotic results closely predict performance of practical finite systems. We demonstrate that the simple feedback scheme yields most gain for either low system loads or low SNR. The power saving is in the order of 1-2dB per signature for a wide range of system loads and SNRs.
