Abstract

We implement a dirty-paper coded framework for the cognitive radio channel.We assume that the cognitive user has non-causal knowledge about the primary user's transmissions. Thus the secondary receiver can employ dirty-paper coding to counter the effect of any interference from the primary user. In addition, we consider a situation where the introduction of the cognitive user should not affect the performance of the primary system - nor should the primary system have to change its encoding/decoding process. For the primary user we use a low-density parity-check code and a 4-ary pulse amplitude modulation format. For the cognitive user, we propose a dirtypaper coding scheme which employs trellis-coded quantization as the source code and an irregular repeat-accumulate code as the channel code. At a transmission rate of 1.0 bits/sample, the designed dirty-paper coding scheme operates within 1.23 dB of the theoretical limit.

Conference	IEEE International Conference on Communications 2010
Abbreviated title	ICC 2010
Country	South Africa
City	Cape Town
Period	23/05/10 → 27/05/10
Other	The IEEE Communications Society will hold its 2010 flagship conference, International Communications Conference (ICC2010) in Cape Town, South Africa. This will be the first time that ICC has been held in Africa and with Cape Town being voted one of the most beautiful cities in the World, this promises to to be an exceptional conference. Conference participants will have a wide range of exciting options to add to their conference tour: hikes up the famous Table Mountain; whale watching; tours of the Cape Winelands, Robben Island and even CapePoint where two oceans meet. The FIFA World Cup Soccer tournament, held all around South Africa starts just after the conference ends.
