N2 - Cyclic prefix (CP) insertion is the most common way for inter-symbol interference (ISI) suppression, however, detrimental to the high-speed data transmission demand for its waste of spectrum resources. To solve this problem, a CP-free hybrid-carrier(HC) scheme is proposed in this paper. In the proposed scheme, the inherently relational process between circular convolution and Fourier transformation is utilized through zero-padding and interval extraction to maintain the cyclic characteristic of the received data block instead of the conventional CP insertion. Both analytical and simulation results are provided to demonstrate the practicability and the superiority of the proposed scheme, in term of bit error rate(BER) performance. Moreover, the proposed CP-free HC-FDE is also proved to be more spectral effective compared to the conventional FDE schemes.
