摘要： A de-interleaving circuit that performs a time de-interleaving process on an interleaved block of an interleave signal includes: an input buffer, buffering multiple information units included in a time interleaved block; a writing address generator, generating multiple writing addresses according to a predetermined rule to write the information units buffered in the input buffer to a memory; a reading address generator, generating multiple reading addresses according to the predetermined rule to read the information units from the memory; and an output buffer, buffering the information units read from the memory. The information units are stored in multiple tiles of the memory. The tiles correspond to multiple regions of the time interleaved block, the multiple regions include a first region and a second region, and the dimensions of each tile in the first region are different from the dimensions of each tile in the second region.

摘要： Methods and devices for encoding and interleaving data packets for broadcast and for de-interleaving and decoding data packets in a communication system eliminate detrimental biasing effects by using pseudo-random M-sequence bit encoding as part of the turbo encoding and decoding. The use of pseudo-random M-sequence bit encoding mitigates biasing effects that may otherwise be introduced if conventional r-c interleaving is applied to long turbo encoded data which would degrade reception in the presence of broadcast interference.
