This paper introduces a power loading strategy for relays to be used in a cognitive scenario. A cognitive relay node allows unlicensed (secondary) users to concurrently operate with licensed (primary) users, thereby improving spectral efficiency. The dynamic spectrum access in an OFDM-based cognitive relay network may lead to unwanted interference to the primary user from the side lobes of the secondary users. Two judicious algorithms are formulated by means of which the cognitive relay meets… CONTINUE READING
