Hybrid Prefix OFDM Transmission Toward Future Wireless Communications

Prefix-based multicarrier transmission is in wide application in current wireless communications, at the expense of extra redundancy and reduced spectral efficiency.In this contribution, we propose a novel hybrid prefix (HP) structure, which can offer higher spectral efficiency for orthogonal frequency division multiplexing (OFDM) based future NEFF D94QFM1N0B N50 Built In 90cm 3 Speeds A Chimney Cooker Hood Stainless touch wireless communications, such as 5G and beyond systems.Compared with the conventional prefix aided OFDM scheme, the proposed HP-OFDM scheme is capable of reducing the average length of the prefix with the aid of a proposed low-complexity detector for efficient signal restoration.

We also quantify the signal to interference plus noise and the achievable rate of the proposed HP-OFDM scheme through a theoretical analysis.Furthermore, the bit-error rate (BER) of the proposed HP-OFDM is also theoretically derived.Our scheme results demonstrate that HP-OFDM is capable of reducing the prefix overhead by 50% compared with prefix-aided OFDM, while Basketball - Balls - Accessories achieving a BER comparable to that of prefix-aided OFDM.
