Abstract
Multiband Keying (MBK) has been proposed as a means of modulating information bits into Ultra Wideband signals. In this paper we concern the Multiband Keying modulation employing MPSK signals in each subband. The optimal receiver for the MBK symbols over AWGN channel and the corresponding Maximum Likelihood (ML) decision rule have been presented and its performance is evaluated through analysis and simulation. An efficient algorithm based on a depth-first tree search is also introduced in order to simplify the Maximum Likelihood detection. It is shown by simulation that while the proposed algorithm significantly reduced the computational complexity, the performance in terms of symbol error rate is very close to that of the optimal ML receiver. © 2004 IEEE.
