Abstract: Disclosed is a method for analyzing the performance of a physical layer network coded system in a nakagami fading channel. The method analyzes the performance of a bidirectional relay system to which a physical layer network coding is applied and an average final symbol error rate in the nakagami fading channel. The present invention induces the upper limit of the average final symbol error rate with a closed formula by inducing the character of a gamma random variable which shows a probability character of the nakagami fading channel and applying the upper limit for a Gaussian function.

Abstract: The present invention discloses a hierarchical spatiotemporal code system. A hierarchical spatiotemporal code system according to an embodiment of the present invention includes: a combiner for synthesizing a plurality of signals through code combination when receiving the plurality of signals using a plurality of antennae; a BCJR decoder for space-time trellis decoding the signal code-combined by the combiner using a previously calculated first log likelihood ratio (LLR) value and outputting a second LLR value as a result; a subtracter for outputting the difference between the second LLR value and the first LLR value; a de-interleaver for de-interleaving the difference between the first LLR value and the second LLR value; and a turbo encoder for channel-decoding the de-interleaved value and updating the first LLR value.
