Adaptive code allocation in multicode-CDMA for transmitting H.263 video
B. Deep, Wu‐chi Feng · 2003
This paper proposes a new way to incorporate H.263 video into existing voice/data code-division multiple access (CDMA) networks using a multi-code access protocol. A channel allocation policy is proposed that "shares" codes for larger I-frame video transmission and allocates a fixed number of codes for P-frame transmissions. The base station in a given cell of a CDMA network controls this allocation method, but bandwidth access distribution is based on both mobile host requests and base station forced requests. This scheme allows more efficient allocation of resources in the bandwidth-limited wireless spectrum and improves the quality of service (QoS) of video traffic over this lossy environment.
