According the high dynamic characteristic of TT&C signals,a fast synchronization scheme for DS/FH hybrid spread spectrum signals is proposed. 针对航天测控信号的高动态特点,提出了直扩/跳频混合扩频(DS/FH)测控信号的一种快速同步方案。 更多例句>> 6...
The second 802.11 variation used DSSS and specified a 2Mbps-peak data rate with optional fallback to 1Mbps in very noisy environments. 802.11, 802.11b, and 802.11g use the DSSS spread spectrum. This means that the underlying modulation scheme is very similar between each standard, enabling all...
This includes an RTP packetization scheme to control the packet size and to improve the error-resilient decoding of the partitioned video signal. The paper includes the simulation results showing the effects of the receiver design and diversity on the quality of the received video signals....
