Abstract :
This paper promises a chip-by-chip channel estimation method for time domain spreading MC-CDMA systems to allow the use of MMSEC. MMSEC effectively compensates the loss of orthogonality among spreading codes, so that we can realize high communication quality even in very fast fading environments. Moreover, the chip-by-chip channel estimation method makes it possible to freely select the time domain or frequency domain as the spreading domain of data symbols.
