摘要： An MIMO receiver and MIMO communication system which can have a small hardware scale even if the number of antennas used for MIMO communication. In a radio communication device (200), a receiving section (220) receives a spatially multiplexed signal generated by mutually-different and spatially multiplexing transmission signals, a first signal demultiplexing section (230) subjects a linear operation to the received spatial multiplexed signal to demultiplex the spatial multiplexed signal, and a second signal demultiplexing section (240) demultiplexer the demultiplexed spatially multiplexed signal into the transmission signals. When the received signal is demultiplexed by a single demultiplexing, as the number of multiplexed spatial multiplexed signal increases, the demultiplexer becomes complicated, and the hardware scale increases. When the received signal is demultiplexed by a plurality of demultiplexings, the hardware scale is relatively small.

摘要： In such a relationship between information transmitted by a primary BCH, for example, and information transmitted by a non-primary BCH as a case of the transmission for a first information sequence that is easy to keep receiving quality and a second information sequence that is difficult to keep receiving quality, a transmitting device and a receiving device are disclosed for making it possible to improve an error rate of the second information sequence. In the devices, an encoder (102) encodes a non-primary BCH information sequence (Sn) with a long code length including a primary BCH information sequence (Sp). On the receiving side, a non-primary BCH information sequence is decoded with a long code length by using the received primary BCH value. With this, a higher encoding gain than encoding only with the non-primary BCH information can be obtained, so that a receiving characteristic of the non-primary BCH can be improved.
