Abstract:
A resource block (RB)-based multicarrier modulation (MCM) transmitter and receiver structure for spectral agile systems are disclosed. The transmitter and the receiver are capable of sharing opportunistically available and non-contiguous channels with other users. The RB-MCM partitions the available spectrum, contiguous or non-contiguous, into multiple RBs (same or different sizes), applies a baseband MCM or single carrier modulation, or coded single carrier or multicarrier schemes in each RB with a type of spectral leakage reduction technique, and applies RB modulation for each RB to modulate the signal from baseband to the frequency band of that RB. At the receiver, the received signal may be filtered and RB demodulation may be applied to put each RB signal in baseband and a baseband multicarrier or single carrier or coded single carrier or coded multicarrier demodulation may be applied to each RB signal. Different RBs may use different modulation schemes.
Abstract:
Systems and methods for providing orthogonal frequency division multiplexing-offset quadrature amplitude modulation (OFDM-OQAM) structure may be disclosed. For example, a synthesis filter bank (SFB) and/or an analysis filter bank (AFB) for a filter length may be derived. The filter length may be odd. Additionally, the AFB may be an inverse discrete Fourier transform (IDFT)-based AFB and/or a discrete Fourier transform (DFT)-based AFB.
