Abstract

A cognitive interference channel consists of two single-user links, one licensed to use the spectral resource (primary) and one unlicensed (secondary or cognitive). According to the cognitive radio principle, the activity of the secondary link should not interfere with the performance of the primary. The cognitive transmitter is allowed to access the channel only when sensed idle. In this paper, the advantages of having the cognitive transmitter acting as a "transparent relay" for the packets of the primary are investigated in terms of stable throughput (packets/slot). The analysis accounts for random packet arrivals, sensing errors due to fading at the secondary link, and power allocation at the secondary transmitter based on long-term measurements.
