Sammanfattning

This paper describes two interleaver structures that reduce the memory requirement for the storage of interleaver rules. The first structure offers memory reductions of more than 50%, compared to storing the entire interleaver vector. The second structure is useful when a range of interleaver sizes are to be stored, offering memory reductions asymptotically approaching 50%. By combining the two structures, a total memory reduction of approximately 75% is achieved. This is obtained without any significant reduction of the error correcting performance of the codes
