摘要： The present invention relates to the field of MIMO wireless communication. Disclosed are a method for combining signals from multiple channels in a multi-antenna receiver and its apparatus. In the present invention, weight values corresponding to each antenna are calculated based on noise estimates or SNRs obtained from channel estimation, and a weighted combination is performed on each signal after channel equalization, which can effectively reduce impact of noises on signals and improve performances of receivers. Weight values are calculated for each subcarrier of each antenna based on noise estimates or SNRs, and a weighted combination is performed in subsequent step, which can further improve performances of OFDM receivers for a OFDM system.

摘要： A mobile communication method based on a mobile communication terminal is provided, wherein a communication unit of the mobile communication terminal is adapted to working in at least two communication modes, and an antenna assembly of the mobile communication terminal is adapted to selectively working in different communication modes or in a combination of different communication modes. The method includes: selecting, based on a communication mode and a service type of the mobile communication terminal, a coupling relationship between the antenna assembly and the communication unit, so that the mobile communication terminal can work in various working modes; and if the communication mode and/or the service type of the mobile communication terminal changes, adjusting the coupling relationship between the antenna assembly and the communication unit based on the change. The mobile communication terminal using the method has characteristics of small size, low cost and less difficulty to design.
