Abstract
With the increasing number of wireless communication devices, bandwidth becomes the precious resource. How to improve the bandwidth ef ciency is the important issue. Partial response (PR) signaling is bandlimited signaling. Because PR signaling can achieve maximum bandwidth ef ciency, PR signaling is widely applied to the wireless communication. However, because the impulse response of the bandlimited signal is in nite, it is not suitable for the burst transmission and low latency scenarios. In this thesis, we propose the multicarrier orthogonal multirate (MC-OMR) modulation which combines multicarrier modulation and OMR modulation which has been proposed. The MC-OMR waveform can have high energy compactness by designing the digital lter. By doing so, in practice, if the transmitted waveform is the truncation version of the MC-OMR waveform, the impact of the truncation on the data loss will be less signi cant. Therefore, the MC-OMR is suitable for the burst transmission. Moreover, according to the energy distribution property of MC-OMR signal, we propose the two truncation methods. In order to decrease the implementation complexity, we propose the ef cient structure of MC-OMR system.
