Wireless packet data transmission
MRW wrote:
Hello again!
I know some of you guys deal with propagation effects, so I figured I
could ask a related question.
In my understanding, a packet is just a way to sectionalize and
categorize individual bits. One group would represent the destination/
address/header. Another would be the actual data (or payload), and
then, maybe a trailer section. Is this a correct assumption?
In wireless transmission, where multipath effects are present, how
does the receiver actually "know" if the order of bits are correct
when processing the packets?
Thanks!
Google "Cyclic Redundancy Check." Or, CRC for short ...
