Abstract
Non-coherent ultra-wideband (UWB) systems have attracted great attention due to their low complexity, and without the need of channel estimation. In order to improve the transmission reliability, polar codes were recently introduced into non-coherent UWB systems because of their capability of approaching the Shannon channel capacity, and their low complexity in both coding and decoding. In the case of polar codes with medium and short length, the bit error rate (BER) performance of coded incoherent UWB systems is limited to incompletely channel polarization, poor Hamming distance and the sensitivity of successive cancellation (SC) decoding resulting in error propagation. In order to improve the performance of coded systems using polar codes with medium and short length, Spinal-Polar codes were recently presented, in which inner codes and outer codes are complementary, and the outer codes have good pseudo-random characteristics and error correction performance in the case of short length. Therefore, in this paper, the interleaved Spinal-Polar codes are introduced into the non-coherent UWB systems. Simulation results show that the interleaved Spinal-Polar codes can effectively improve the BER performance of the coded non-coherent UWB systems using polar codes with medium and short code length.
