The capacity of channels with fading and burst errors
Abstract
The capacity of typical channels with memory is calculated, when a channel state information is used besides interleaving. The knowledge of the channel state allows full exploitation of the increased channel capacity. A Gilbert-Elliott-burst channel and a slowly fading Rayleigh channel are considered. For the burst channel with certain parameter values, the capacity can be more than doubled using state information. For the Rayleigh case, the instantaneously measured SNR can be used by a decoder in addition to hard or soft receiver decisions. This yields an additional gain up to 3 dB compared with mere interleaving. Practical applications for decoding schemes are discussed.
