Aprašymas

The United States Air Force relies heavily on computer networks for everyday operations. The medium access control (MAC) protocol currently used by most local area networks (LAN) permits a single station to access the network at a time (e.g. CSMA/CD or Ethernet). This limits network throughput to, at most, the maximum transmission rate of a single node with overhead neglected. Significant delays are observed when a LAN is overloaded by multiple users attempting to access the common medium. In CSMA/CD, collisions are detected and the data sent by the nodes involved are delayed and retransmitted at a later time. The retransmission time is determined with a binary exponential back-of algorithm. Code Division Multiple Access (CDMA) is a technique that increases channel capacity by allowing multiple signals to occupy the same bandwidth simultaneously. Each signal is spread through multiplication with a unique pseudo-random code that distinguishes it from all other signals. Upon reception, the signal of interest is despread and separated from other incoming signals by multiplying it with the same exact code. With this technique, it is possible for multiple stations to transmit simultaneously with minimal ill effects.
