Abstract

An approach is provided for channel interleaving. A plurality of symbols are received and partitioned into a plurality of subblocks. The subblocks form a plurality of subsequences. A first output sequence is generated from the subsequences. The subsequences of the first output sequence is selected and punctured to generate a second output sequence, and interleaving the second output sequence.

Description

[0001] related application [0002] This application claims U.S. Provisional Application No. 60 / 680,285, filed May 12, 2005, entitled "Enhanced Channel Interleaver For Supporting Communication Service"' and filed on May 4, 2005, pursuant to 35 U.S.C. § 119(e). US Provisional Application No. 60 / 677,495, entitled "Method and Apparatus for Code Puncturing and Channel Interleaving," filed on , which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to communications, and more particularly to providing channel interleaving. Background technique [0004] Radio communication systems, such as cellular systems such as spread spectrum systems such as Code Division Multiple Access (CDMA) networks, or Time Division Multiple Access (TDMA) networks, provide users with the convenience of mobility with a rich set of services and features. This convenience has led to the mass adoption of wireless communication systems by a growing nu...
