Methods and apparatus are provided for inserting data symbols and pilot symbols in an OFDM (orthogonal frequency division multiplexing) transmission resource utilizing frequency hopping patterns for the data symbols and/or the pilot symbols. Data symbols and pilot symbols are allocated for down link (base station to mobile station) and up link (mobile station to bases station) transmission resources in a two-dimensional time-frequency pattern. For each antenna of a MIMO-OFDM (multiple input multiple output OFDM) communication system, pilot symbols are inserted in a scattered pattern in time-frequency and data symbols are inserted in an identical frequency-hopping pattern in time-frequency as that of other antennas.
A method for inserting data and pilot symbols into an Orthogonal Frequency Division Multiplexing (OFDM) transmission resource for transmission on N transmitting antenna where N≧2, the OFDM transmission resource having a time domain and a frequency domain, each OFDM transmission resource comprising a plurality of OFDM symbols, the method comprising the steps of:
An OFDM transmitter comprising:
