By exploiting the separable rate expression with improper Gaussian signaling, we propose a separate covariance and pseudo-covariance optimization algorithm, which is guaranteed to improve the users' rates over the conventional proper or circularly symmetric complex Gaussian signaling. In particular, for the pseudo-covariance optimization, the semidefinite relaxation (SDR) technique is applied to provide a high-quality approximate solution. For the special case of two-user MISO-IC, the SDR technique yields the optimal pseudo-covariance solution. © 2013 IEEE. | Source Title: | ICASSP, IEEE International Conference on Acoustics, Speech and Signal Processing - Proceedings | URI: | http://scholarbank.nus.edu.sg/handle/10635/70953 | ISBN: | 9781479903566 | ISSN: | 15206149 | DOI: | 10.1109/ICASSP.2013.6638486 |
