English abstract:
In 3GPP LTE communication systems, channel
state information is fed back by means of the channel quality
indicator, the precoding matrix index and the rank indicator. This
limited feedback information is used to adapt the transmission
scheme such as to improve the throughput and to reach a certain
target block error ratio. Based on the channel impulse response
we calculate the interference power caused by insufficient cyclic
prefix length. By accounting for this inter symbol and inter
carrier interference power in the feedback calculation, we obtain
an improved throughput in OFDM systems.
