....gaps caused by bursty errors using parallel channels for a very short time. While the usage of parallel channels will lead to a performance degradation of other mobiles, this mechanism will be used only for I frames. Different mechanisms how to use parallel channels were already investigated [7]. The mechanisms work distributed and autarkic. Thus a minimum of signaling is necessary. Because the performance of the mechanism is correlated on the design of the spreading sequences, we want to investigate how such sequences can be obtained and which performance gain can be achieved. Optical ....

....limits the maximum number of retransmissions for medium access control (MAC) packets, not considering the whole transport segment and their QoS requirements. It seems to the authors that this scheme will not support properly QoS for higher protocol layers. 2 SMPT approach Therefore Fitzek et al. [2] developed a Simultaneous MAC (Medium Access Control) Packet Transmission (SMPT) scheme for Multi Code Code Division MultipleAccess (MC CDMA) environments. The SMPT scheme deliver transport layer segments with high probability within a permissible delay bound. The approach works as follows: ....
....packet suffer by the preceding retransmissions. In case the bounded delay can not be achieved, all packets of this transport segment are discarded from the MAC queue. The transport segment is counted as lost, but it will lead to an increased SINR for other wireless devices. We refer the reader to [2, 3] for details. However, the SMPT performance depends significantly on the influence of parallel channels. Therefore the motivation for the present paper is to show the impact of different spreading sequence allocations schemes in terms of SINR. 3 SMPT based CDMA channel We consider the K user ....
