This research proposes integrated systems consisting of multicarrier code-division multiple-access (Multicarrier CDMA) with Pure Aloha (P-Aloha)scheme, named multicarrier CDMA P-Aloha. The performance analysis of the system is stated as throughput. In multicarrier CDMA P-Aloha the initial data is serial-to-parallel converted to a number of lower rate data streams. Each stream which consists of a part of the initial data called sub-packet will be then direct sequence spread-spectrum modulated using specific spreading code for each user, and all the DS-SS signals are transmitted in parallel on different subcarriers. Results show that the system has high throughput for high bit rate signal transmission. It is also shown that the throughput of the system improves as the number of subcarriers and the length of single-carrier code increase, while the increase of subpacket length degrades the throughput of the system.
