Damped Zero-Pseudorandom Noise OFDM Systems

This paper proposed a new OFDM scheme called damped zero-pseudorandom noise orthogonal frequency division multiplexing (DZPN-OFDM) scheme. In the scheme, ZPN-OFDM non-zero part to reduce guard interval energy as well mutual interference power in-between data and training blocks, conservative pseudo-noise conventional properties required for channel estimation or synchronization. The motivation of this is long working in wide dispersion channels, where significant waste if used BER performance degradation. Also, solve spectrum efficiency loss problem, doesn’t duplicate interval. Both detailed analysis simulation results show that DZPN-OFDM can, indeed, offer bit error rate, improvement.
