Abstract:
1. A method of generating an orthogonal frequency division multiple access (OFDMA) symbol, the method comprising: receiving incoming data packets; determining a first index associated with each data packet of the incoming data packets; storing each data packet of the incoming data packets at an address in a memory according to the first index associated therewith; selecting a subcarrier associated with the OFDMA symbol; determining whether to transmit pilot information or non-pilot information on said subcarrier; reading a stored data packet from said memory in response to determining that non-pilot information will be transmitted on said subcarrier and modulating said subcarrier using information contained in said stored data packet; generating a pilot symbol associated with a next subcarrier of the OFDMA symbol; incorporating said pilot symbol in the OFDMA symbol in response to determining that the next subcarrier is associated with transmission of said pilot information; and holding said pilot symbol in response to determining that that the next subcarrier is associated with transmission of said non-pilot information.
