| Abstract: |
Semi blind impulse radio (IR) is a low complexity receiver, which improves performance by employing prior knowledge of the pulse transmission times of all other users. In this paper we investigate the optimization of the operation of a semi-blind IR system as a multiuser, multiple-access system. We show that optimal semi-blind IR has significant performance improvement over a code division multiple access (CDMA) system. This performance increase is measured by the achievable rate region, and it is shown that using semi-blind IR, the rate of at least one of the users can be made higher, without decreasing the rate of any user. |
