Embodiment Construction

[0038] The present invention will be described in detail below through the accompanying drawings and examples.

[0039] figure 1 It is a device schematic diagram of an embodiment of the present invention.

[0040] The independent Rayleigh channel generator is used to generate the required number of independent Rayleigh channels. Its characteristic is that when the mean, variance and number of required independent Rayleigh channels are input, the required number of independent Rayleigh channels can be quickly generated.

[0041] The channel correlation matrix generator 1 is used to generate a segmented channel correlation matrix. It is characterized in that, according to the obtained correlation coefficients of the sending end, the relay end, and the receiving end, the channel correlation matrix from the sending end to the relay end and from the relay end to the receiving end is quickly generated.

[0042] The channel correlation matrix generator 2 is used to generate the ch...

Abstract

The invention discloses a quick channel simulation method and a quick channel simulation device of an amplify-forward relay system. The quick channel simulation can be performed for the amplify-forward relay system, a general simulated channel from a transmitting terminal to a receiving terminal can be rapidly generated after number of antennas and correlation coefficient of the transmitting terminal, a relay terminal and the receiving terminal and independent average of Rayleigh channels and variance are acquired. Correlation channels are established from a transmitter to the relay terminal and the terminal to a receiver, then correlation matrix of the general simulated channel is calculated according to the correlation coefficient of the transmitting terminal, the relay terminal and the receiving terminal; and finally a channel model is established according to the correlation matrix of a general channel. The quick channel simulation method for the simulations of the amplify-forward relay system has the advantages that correlation of a base station terminal, the relay terminal and the receiving terminal and transceiver link correlation are fully taken into the consideration of the established model, and an entire link can be simulated truly and accurately by the model; definition is strictly abided in cultivating the correlation coefficient to make the same accurate and reasonable; and the whole link can be simulated from the transmitter to the receiver to achieve effects of convenience and conciseness.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to channel modeling and cooperative communication channel modeling. Background technique [0002] In wireless communication, MIMO technology has been regarded as one of the key technologies to realize high-speed information transmission. MIMO technology has made a key contribution to improving the capacity of wireless communication systems. MIMO (Multiple-Input-Multiple-Output technology) realizes data multiplex transmission by increasing the number of transceiver antennas at the transceiver end, and finally achieves the effect of increasing the information transmission rate and improving the capacity of the communication system. [0003] Because the capacity of the traditional cellular network is limited, and the future communication system requires high-speed and large-capacity information transmission, relay technology, as a key technology to improve th...
