Direct sequence spread spectrum uses a long pseudo noise code that is
added with the data sequence to get the spreaded signal or sequence. so each
user is identified uniquely by the pseudo noise code, In case of frequency hopping spread spectrum every channel in uniquely identified by the hope in frequency during every time slot. That is the signal is of a particular frequency in a particular time slot and changes to another frequency (hopes) during another time slot.
