PARALLEL INTERFERENCE CANCELLATION APPARATUS AND METHOD FOR A REVERSE LINK IN A HRPD SYSTEM

摘要

The present invention provides a parallel interference cancellation apparatus for a reverse link in a high rate packet data system and the method thereof. The method therein includes the following steps: A. transferring payload size, code rate and repetition parameter to a parallel interference cancellation unit according to the definition in the high rate packet data protocol; B. the parallel interference cancellation unit executes the following parallel interference cancellation steps: B1. using matched filters to filter sub-frame data of the user, and sending a plurality of filtered sub-frame data to a storage unit one by one; B2. combining a plurality of filtered sub-frame data in the storage unit according to the payload size, code rate and/or repetition parameter, so as to generate one-shot data; B3. reacquiring full-frame data in agreement with the modulation rate from the one-shot data according to the payload size, code rate and/or repetition parameter; and B4. executing the parallel interference cancellation for the reacquired full-frame data.
