“…Kaissoine et al use a CA method, based on using a transmitter chain by frequency band, for more than two frequency bands dedicated for modulation and demodulation of Quadrature Phase Shift Keying (QPSK) modulated signals. In other words, in order to have three frequency aggregated bands, one should use three RF transmitters and three Local Oscillators (LO) for a complete modulation and demodulation process [4]. This equipment design increases the energy consumption and the production cost of the system.…”

To increase the data throughput in Radio Frequency (RF) communication, several coding techniques, different modulations and other secondary parameters can be improved, however the most important factor is the available bandwidth. Carrier Aggregation (CA) is the method proposed in the standardization of LTE-Advanced (LTE-A) by 3rd Generation Partnership Project (3GPP) in order to achieve up to 100 MHz of bandwidth. In this paper a method for generating carrier aggregated Orthogonal Frequency Division Multiplexed (OFDM) signals using a single transmitter chain is presented, moreover the demodulation results obtained by a Tri-Phase Demodulator (TPD) are presented.
