Abstract:
1. A method of transmitting data on a link from a first radio to a second radio across a plurality of timeslots in a frame, the method comprising: encoding user data using a forward error correcting code to generate an encoded bit sequence, wherein the user data is data for a single user; generating a first spread portion of the encoded bit sequence with a first spreading sequence associated with a first portion of the frame, the first spreading sequence based on a first channelization code and a first scrambling code; generating at least a second spread portion of the encoded bit sequence with a second spreading sequence associated with a second portion of the frame, the second spreading sequence based on a second channelization code and a second scrambling code, wherein the first channelization code differs from the second channelization code according to a predetermined code variation pattern; and transmitting, from the first radio to the second radio, the frame including the first spread portion and the at least second spread portion of the encoded bit sequence.
