This work proposes a methodology for the phase estimation in sub-bands of a non-uniform response channel. The novelty of this proposal lies in the use of a modulation format in QSPK (Quadrature Phase Shift Keying) quadrature-phase modified as a test signal for the phase estimation that eliminates the ambiguity issue. The methodology here proposed is verified experimentally using a defective RF cable as transmission channel and
thus achieving data transmission rates of 20 Kbaud in a 120 cm distance in a frequency band between the 50 kHz y 276 kHz.
