hi all,
I am not very familiar with DSSS.
I want to know how despreading is achieved? by simply multiplication with the corresponding PN ? or It depends on how the signal is spreaded?
Because I found that the spreading in 802.15.4 is achieved by mapping not multplication. I do no know how despreading will be achieved?
thanks!
