Broadband Amplifier Gain Slope Equalization Filter
نویسندگان
چکیده
Since the achievable gain of transistors typically falls off as the frequency increases, an equalization filter with positive gain slope is necessary to compensate for the gain roll-off of broadband amplifiers. This paper proposed an novel equalizer structure and design a equalization filter by applying this novel structure and a modified SIW-PBG (Substrate Intergrated Waveguide-Photon BandGap) filter. The numerical simulated results show that the proposed design of Gain Slope Equalization Filter has a positive gain slope from 8.5 GHz to 18.5 GHz with good impedance matching,low excess loss,and good selectivity.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

The base-band analog processor performs necessary signal processing on the 150 MHz base-band signal in the transmit and receive signal paths for a wide-band wireless local area network. The individual channel characteristics depend on the RF signal fade and interference. Broadcasting to multiple appliances requires channel equalization at the receiver. In the receive (Rx) section, the wide-band...

متن کاملMultiple-point equalization of room transfer functions by using common acoustical poles
A multiple-point equalization filter using the common acoustical poles of room transfer functions is proposed. The common acoustical poles correspond to the resonance frequencies, which are independent of source and receiver positions. They are estimated as common autoregressive (AR) coefficients from multiple room transfer functions. The equalization is achieved with a finite impulse response ...
