    Abstract: PROBLEM TO BE SOLVED: To enable transmission at a fast bit speed by giving an arbitrary order to symbol components of a vector signal and allowing the receiver to determine components of a transmit symbol after determining the best rearrangement of sent components, starting detect processing from the start level, and off-setting interference from lower levels when there are interferences for the respective levels. SOLUTION: The receiver 200 includes RF receiver sections and they interface with the antennas respectively. The receiver 200 further includes a preprocessor 60, a symbol processor 65, and a multiplexer 70. The processor 60 receives signals from the (n) antennas as signal vectors and preprocesses the received signal vectors to remove the interference between the signal components forming the vectors. This process includes a process for subtracting the interference due to a sent symbol detected before from a currently processed vector.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for increasing the capacity of a multiple-input and/or multiple-output system. SOLUTION: The method to be used by a system for communicating primitive data streams in this invention is characterized by that the method includes a step of transmitting at least part of each of a plurality of processed sub- streams, where the primitive data stream includes a plurality of sub-streams and each sub-stream includes a plurality of sub-stream component data streams. Each processed sub-stream represents each sub-stream, each processed sub-stream includes a plurality of strata, each stratum of each processed sub-stream represents one of the component data streams represented by the processed sub-streams and one of the sub-stream components respectively.
