    Abstract: Apparatus for reducing adjacent channel interference between proximate wireless communication units. Each wireless communication unit includes a digital baseband circuit and an analog baseband circuit. The digital baseband circuit includes at least one group delay compensation equalizer and at least one finite-impulse response (FIR) filter. The analog baseband circuit includes a radio (transmitter section), a power amplifier and a narrowband filter. The narrowband filter compensates for deficiencies of the power amplifier including distortion and radio frequency (RF) power spill over. The group delay compensation filter compensates for undesired characteristics (e.g., group delay variation) exhibited by the narrowband filter.

    Abstract: Aparato para reducir interferencia de canal adyacente entre unidades de comunicacion inalámbrica proximas. Cada unidad de comunicacion inalámbrica incluye un circuito de banda base digital y un circuito de banda base analogico. El circuito de banda base digital incluye al menos un ecualizador de compensacion de retardo de grupo y al menos un filtro de respuesta de impulso finito (FIR). El circuito de banda base analogico incluye una radio (seccion de transmisor), un amplificador de potencia y un filtro de banda angosta. El filtro de banda angosta compensa las deficiencias del amplificador de potencia, que incluyen distorsion y desbordamiento de potencia de radio frecuencia (RF). El filtro de compensacion de retardo de grupo compensa las características no convenientes (por ejemplo, variacion de retardo de grupo) presentadas por el filtro de banda angosta.
