An apparatus for wireless communication is provided. The apparatus includes a processing circuit configured to receive data to be wirelessly transmitted within a predefined frequency range. Further, the processing circuit is configured to generate a first radio frequency transmit signal of a first frequency range based on the data, and to generate a second radio frequency transmit signal of a second frequency range based on the data. The first frequency range and the second frequency range are subranges of the predefined frequency range. The apparatus further includes a front-end circuit configured to supply the first radio frequency transmit signal to a first antenna, and to supply the second radio frequency transmit signal to a second antenna.

A MIMO symbol detection and search method, a decoding circuit and a receiving antenna system are provided. The signal detection and search method includes the following steps. A symbol search tree is obtained, and a plurality of candidate symbols at each layer of the symbol search tree are sorted. The candidate symbols are traversed in sequence at each layer of the symbol search tree. At each layer of the symbol search tree, if a cumulative partial Euclidean distance is greater than or equal to a threshold, un-scanned candidate symbols are excluded. If the cumulative partial Euclidean distance is less than the threshold, the threshold is updated by the cumulative partial Euclidean distance. When all of the candidate symbols have been calculated, an estimated symbol combination is outputted, and the scan of the symbol search tree is terminated.
