Abstract

The invention provides systems and methods of multi-antenna emission, single-antenna receiving and multi-antenna transmission. The multi-antenna emission system comprises at least two antennas, at least two emission modules and a protocol layer demultiplexer, wherein each emission module converts a to-be-emitted data packet to wireless signals; the protocol layer demultiplexer comprises a check detection unit, a sorting unit and an output unit; the check detection unit detects whether the to-be-emitted data packet has a check bit and if not, a check bit is added; the sorting unit adds a sequence number bit to the data packet outputted by the check detection unit; and the output unit outputs the corresponding data packets to the at least one emission module for emission according to the sequence of the sequence number bits. The fast fading problem can be solved, the communication stability of an uplink communication system can also be ensured, occupancy of too many bands is not needed,a downlink communication system is not disturbed, and on the premise of not increasing the number of receiving antennas, the communication quality of the multi-antenna transmission system is ensured.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a wireless transmission system and method, in particular to a multi-antenna transmission, single-antenna reception, and multi-antenna transmission system and method. Background technique [0002] All wireless communication is based on the propagation of electromagnetic waves in space to achieve information dissemination. The propagation of electromagnetic waves in free space mainly has four modes: direct radiation, reflection, scattering and diffraction. The signal has changed somewhat. The influence of wireless channel on signal transmission mainly includes transmission attenuation, frequency selective fading caused by multipath propagation, time selective fading caused by time variation and space selective fading caused by angle spread. [0003] When the transmission power of wireless transmission is constant, the transmission distance of the wireless signal is l...
