摘要： In a system (41) like CDMA, SC, OFDM, OFDMA, etc., a method is disclosed for computing and using the parameter d (42) for all blocks. The Bit Interleaver uses a constant parameter (named "d", and it equals for example 16 in 802.16), in order to perform its inn permutations. Improved performance is achieved by manipulating the "d" parameter of the formula per modulation and encoded bloc (43), using data from a table. An example applicable with the current 802.16d (2004) for the "d" parameter is also disclosed (44).
