Abstract

The present invention provides a transmission signal estimation method, system, equipment and storage medium, which are used in a MIMO system. The estimation method includes: receiving external received signals; establishing a quantum population; extracting the optimal probability from the initial probability range of the quantum chromosome Update the initial probability amplitude: get the mutation probability amplitude, mixing probability amplitude and rotation probability amplitude according to the initial probability amplitude; update the initial probability amplitude according to the mixing probability amplitude and rotation probability amplitude, and extract the latest optimal probability amplitude, and increase the number of iterations by one ; Determine whether the number of iterations reaches the iteration threshold: if yes, obtain the estimated signal of the transmitted signal according to the latest optimal probability amplitude; if not, continue to update the initial probability amplitude. The invention adopts the maximum likelihood detection function algorithm to update the probability range of the quantum chromosome so that it approaches the transmission signal and converges; it solves the problem of high signal estimation complexity, reduces the number of searches and reduces the Signal estimation complexity.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, system, device and storage medium for estimating a transmitted signal. Background technique [0002] Usually, the transmitter and the receiver in a Multiple Input Multiple Output (MIMO) system are equipped with multiple antennas. The use of multiple antennas not only provides higher channel capacity, but also transmits signals to the MIMO system. The estimation brings challenges; in general, the zero forcing algorithm (ZF) and the minimum mean square error (MMSE) algorithm are often used for signal estimation. However, when the ratio of the number of transmit and receive antennas is small , the performance of these two algorithms is poor; while the maximum likelihood algorithm (maximum likelihood, ML) has the best performance, but it has high complexity and is not easy to handle. [0003] As an emerging technology, quantum computing is widely used...
