[0030]FIGS. 1 through 7, discussed herein, and the various embodiments used to describe the present invention are by way of illustration only, and should not be construed to limit the scope of the invention. Those skilled in the art will understand the principles of the present invention may be implemented in any similar radio-communication device, in addition to those specifically discussed herein.
[0031] The present invention is directed to a system and method for communication in a radio telecommunication network, and is of particular advantage when applied to a multi-carrier code division multiple access (MC-CDMA) system that includes a pulse-shaping filter on the transmit side. FIG. 3 is a flow diagram illustrating a relevant portion of the process of signal transmission in such a system. At START, it is assumed that the information to be transmitted has been encoded and modulated. The modulated symbols are then spread (step 305) using an appropriate spreading code and provided...
