Multiresolution Decoding Algorithm for Walsh-Hadamard Linear Precoded OFDM


When no channel knowledge is available at the OFDM transmitter, the water pouring strategy is inappropriate and the information sent on one subchannel can irremediably be lost if a deep fade occurs. The role of uniform spreading in Linear Precoded OFDM (LP-OFDM) also known as OFDM-CDMA [1], [2] is to exploit all the frequency diversity of the channel… (More)
