Abstract

The invention provides a faster-than-Nyquist rate block transmission method, a transmitter, a receiver and a system. Code elements to be transmitted are subjected to shaping filtering operation at a faster-than-Nyquist rate, cyclic superposing operation is performed, block symbols capable of keeping the faster-than-Nyquist rate and keeping head-tail circulation, protection intervals are added to symbol blocks, and transmitting base-band symbols are formed. Via the protection intervals, a receiving end is enabled to eliminate ISI caused by a multipath information channel via simple equalization, head-tail circulation block symbols formed via cyclic superposition are used for eliminating self ISI caused by transmission at the faster-than-Nyquist rate via time domain or frequency domain equalization, and therefore demodulation complexity of the receiving end can be lowered.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method, a transmitter, a receiver and a system of a super-Nyquist rate block. Background technique [0002] With the explosive growth of wireless devices in recent years, especially the rapid popularization of smart devices capable of transmitting high-speed multimedia streams, wireless data traffic has shown an exponential growth trend. In the real dilemma of limited total spectrum resources, finding a transmission technology with higher spectrum efficiency is a crucial link in the design of future-oriented wireless communication systems. One of the potential technologies is super-Nyquist transmission (English: Faster than Nyquist, referred to as: FTN), FTN allows data transmission at a code rate higher than the Nyquist rate on the same bandwidth to improve frequency band utilization rate, thus triggering a research boom. [0003] The Nyquist criterion re...
