    摘要: A transmitter for maximizing coding gain by transmitting an input symbol sequence through a plurality of transmit antennas method according to feedback CQIs from a receiver in a 3 Tx-rate 2 communication system. In the transmitter, an S/P converter converts serial modulated data to parallel modulated data. A coder mode decider determines a transmission mode based on the channel quality indicator of each transmit antenna fed back from a receiver. A coder transmits the parallel modulated data through the three transmit antennas according to the determined transmission mode.

    摘要: An apparatus and method for maximizing the efficiency of a power amplifier by reducing the PAPR of a BS in a mobile communication system. A power controller between I and Q channel pulse shaping filters and a frequency converter calculates cancellation signals for signal pulses that increase the PAPR at each sampling period, pulse-shape-filters cancellation signals at the highest levels among the cancellation signals, and adds the filtered cancellation signals to the original signals. Thus, spectral regrowth outside a signal frequency band is suppressed, In the case of a system supporting multiple frequency allocations, the PAPR is controlled for each FA according to its service class. Therefore, minimum system performance is ensured and power use efficiency is increased.
