Library
IS-95A Mobile Station Transmitter
Description
This block interleaves or deinterleaves a data frame for the Access channel or reverse Traffic channel. The interleaving time span is 20 ms. The interleaver is a matrix of 32 rows and 18 columns. The interleaver writes the code symbols into the matrix on a column-by-column basis for all of the input data symbols. It then reads the stored data into the output buffer on a row-by-row basis in accordance with the IS-95A specification to achieve the interleaving functionality. The deinterleaver restores the interleaved symbols to the original order.
