Abstract:
1. Method for performing orthogonal multiple access, the method comprising the steps of: a first subscriber unit within a communication system being assigned a first set of subcarriers comprising a first number of subcarriers, wherein spacing between neighboring subcarriers within the first set of subcarriers is uniform, and wherein the first set of subcarriers are used for transmitting a first single-carrier symbol stream; a second subscriber unit within the communication system being assigned a second set of subcarriers comprising a second number of subcarriers, wherein spacing between neighboring subcarriers within the second set of subcarriers is uniform and wherein the second set of subcarriers are used for transmitting a second single-carrier symbol stream; wherein the first number of subcarriers differs from the second number of subcarriers; wherein the first and the second set of subcarriers are assigned in an orthogonal fashion; and wherein the first and the second set of subcarriers are used for frequency division multiple access between the first and the second subscriber units.
