located in space and surrounded by substantially isotropic lossless dielectric additionally or alternatively the antennas may be separated by a distance in which case phase compensation may be performed on the signal from at least one of the antennas and or the antennas may be separated by a polarizing component therefore for example some embodiments may include antennas that are only partially orthogonal or not orthogonal whereas the use of polarizers ensures that the antennas receive orthogonal or partially orthogonal components of the signal being received fig5 shows an embodiment of a transmitting apparatus 500 the transmitting apparatus 500 includes an encoding interleaving and demodulating block 502 that receives data to be transmitted encodes interleaves and modulates the data according to selected schemes and provides the resulting complex symbols to a combiner 504 which combines the symbols with pilot symbols 506 and training symbols 508 into a frame in a known manner the symbols of the combined frame are provided to an inverse fast fourier transform ifft block 510 which performs the ifft operation and provides the resulting symbols to a prefix add block 512 that adds a prefix to the frame in a known manner the symbols of the frame are then passed to a polarization processing block 514 this block 514 selects a polarization state ps for the frame or at least part of the frame when it is transmitted the polarization processing block 514 produces two channels that are passed to dacs 516 and 518 respectively the output of dac 516.
