OVSF codes assignment and reassignment at the forward link of W-CDMA 3G systems

  title={OVSF codes assignment and reassignment at the forward link of W-CDMA 3G systems},
  author={Angelos N. Rouskas and Dimitrios N. Skoutas},
We examine the problem of assigningandreassigningorthogonal variable spreading factor (OVSF) codes at the forward link in 3G mobile communications systems employing WCDMA. Efficient channelization code management results in high code utilization and increased system capacity. We introduce a new code selection scheme, which, by means of a very simple measure, attempts to mitigate the problem of scattered codes that fragments the capacity of the OVSF code tree. The main advantage of this new… CONTINUE READING
