Apparatus is provided which allows for the receipt and/or transmission of data signals, and, for the received signals, for the subsequent separation of the same into at least two sets of data signals which are orthogonal and provide these sets of data signals to subsequent processing components, whilst maintaining the isolation between the first and second data signal sets. For the transmission of the data signals the first and second sets of data signals are initially separate and then combined into one data set to allow the same to be transmitted.
