Patent ID: 8233554

Claim:
A communications method comprising: forming a data vector comprising N data elements; N≧2; subjecting the data vector to a transformation and forming a transformed vector responsive to said subjecting; inserting at least one pilot symbol into the transformed vector and forming an augmented vector responsive to said inserting; and transmitting by a transmitter the augmented vector; wherein subjecting the data vector to a transformation occurs prior to said inserting at least one pilot symbol into the transformed vector and forming an augmented vector and wherein transmitting by a transmitter the augmented vector comprises transmitting by the transmitter simultaneously in time a plurality of sub-carriers; wherein the transformation distributes an element/component/dimension of the data vector over a plurality of elements/components/dimensions of the transformed vector; and wherein an element/component/dimension of the transformed vector comprises a superposition of values of a plurality of elements/components/dimensions of the data vector.
