Comments on 'Bit Interleaved Coded Modulation'
Caire, Taricco and Biglieri presented a detailed analysis of bit interleaved coded modulation, a simple and popular technique used to improve system performance, especially in the context of fading channels. They derived an upper bound to the probability of error, called the expurgated bound. In this correspondence, the proof of the expurgated bound is shown to be flawed. A new upper bound is a...
متن کاملBit-Interleaved Coded Modulation
The principle of coding in the signal space follows directly from Shannon’s analysis of waveform Gaussian channels subject to an input constraint. The early design of communication systems focused separately on modulation, namely signal design and detection, and error correcting codes, which deal with errors introduced at the demodulator of the underlying waveform channel. The correct perspecti...
متن کاملAdaptive bit-interleaved coded modulation
Adaptive coded modulation is a powerful method for achieving a high spectral efficiency over fading channels. Recently proposed adaptive schemes have employed set-partitioned trelliscoded modulation (TCM) and have adapted the number of uncoded bits on a given symbol based on the corresponding channel estimate. However, these adaptive TCM schemes will not perform well in systems where channel es...
متن کاملBit-interleaved coded irregular modulation
We consider a simple method to improve the adaptiveness and flexibility of bit-interleaved coded modulation (BICM) with different iterative decoding schemes for bandwidth efficient transmission. The basic idea is to apply different signal constellations and mappings within one code word. The combination of different signal constellations allows a fine adaptation of the data rate to the channel ...
متن کاملAdaptive Bit-Interleaved Coded Irregular Modulation
We consider a simple method to improve the adaptiveness and flexibility of bit-interleaved coded modulation (BICM) for various channel models. With state-of-the art adaptive transmission techniques, the raw adaptation of the data rate to the channel characteristics is usually done by selecting an appropriate signal constellation and the fine adaptation is done by changing the code rate. To enab...
