Abstract :
Pulse-position-hopped (PPH) code division multiple access (CDMA) is a new promising multiple-access technique which is very well suited for short-range multipath communications and has several benefits, such as coherent reception and low transmit power density. We analyze the error-correcting capability of a system employing PPH-CDMA. The results show that the system capacity is proportional to the bandwidth, in a similar fashion as for carrier-based transmission techniques
