A study on co-channel interference reduction manipulating PRF in asynchronous UWB-MBOK systems

We present a novel method for co-channel interference reduction in ultra-wideband multiple biphase orthogonal keying (UWB-MBOK) systems. This is achieved by manipulating the pulse repetition frequency (PRF). In the proposed UWB-MBOK systems, the user and data are identified by orthogonal sequence and PRF, while they are identified only by sequence in conventional systems. The result shows the throughput of the proposed systems is higher than that of the conventional one.
