| Abstract: | An original analysis is presented for n/sup k/-PPM in which the information is conveyed by the position of k pulses, each within their own frame of n slots, giving n/sup k/ PPM symbols. Comparisons are made with multiple PPM (MPPM) and it is demonstrated that n/sup k/-PPM offers improved orthogonality, a simplified circuit implementation and comparable receiver sensitivity. |
