Time-Frequency Warped Waveforms

Mostafa Ibrahim, Ali Fatih Demir, Huseyin Arslan

摘要:

即将到来的通信系统在各个方面朝着改进的灵活性前进。提高灵活性对于满足不同的服务要求至关重要。这封信提出了一种新的波形设计方案,利用轴扭曲,使不同的脉冲形状的和平共处。翘曲变换非均匀地操纵晶格样本,并提供灵活性来处理信号的时间-频率占用。所提出的方法能够以准正交的方式利用灵活的脉冲形状,并提高频谱效率。此外,矩形资源块结构,这有助于一个有效的资源分配,也保留了扭曲波形设计。

英文摘要:

The forthcoming communication systems are advancing towards improved flexibility in various aspects. Improved flexibility is crucial to cater diverse service requirements. This letter proposes a novel waveform design scheme that exploits axis warping to enable peaceful coexistence of different pulse shapes. A warping transform manipulates the lattice samples non-uniformly and provides flexibility to handle the time-frequency occupancy of a signal. The proposed approach enables the utilization of flexible pulse shapes in a quasi-orthogonal manner and increases the spectral efficiency. In addition, the rectangular resource block structure, which assists an efficient resource allocation, is preserved with the warped waveform design as well.
