Over the past several years, orthogonal frequency division multiplexing (OFDM) has received considerable attention from the general wireless community and in particular from the wireless LAN (WLAN) ...
To allow for coherent demodulation at the user equipment, reference symbols (or pilot symbols) are inserted in the OFDM time-frequency grid to allow for channel estimation. Downlink reference symbols ...
In this paper we present a set of embedded digital signal processors to build a programmable OFDM receiver that can address a variety of broadcast formats as used for both digital television and ...
