Design of prototype filter for near-perfect-reconstruction overlapped complex-modulated transmultiplexers
Shahriar Mirabbasi, K. Martin · 2003
A simple method for the design of the finite-impulse-response prototype filter for maximally-decimated overlapped complex modulated transmultiplexers with near perfect reconstruction property is presented. The procedure is unified for all values of overlap factor and leads to a prototype filter with excellent frequency selectivity and fast side-lobe fall-off rate. The high stop-band attenuation and fast side-lobe fall-off rate, which is justified analytically, make the proposed filters suitable candidates for high-speed data communication applications employing multicarrier modulation.
