摘要： In a channel search performed first after the installation of a broadcast receiver, a switch is switched to each of an attenuator ATT 5 side and an amplifier Amp 7 side to acquire reception state information (AGC, BER, C/N). The broadcast receiver is provided with a counter 32a for counting the number of receivable channels on each of the amplifier Amp 7 and the attenuator ATT 5. If image/voice can be normally received over the corresponding channel is determined based on the reception state information from reception state information detecting means 31. If it is determined that image/voice can be normally received, the counter of the attenuator side or the amplifier side is incremented by one. Upon termination of the channel search, the two counters are compared and the switch is fixed to the side on which more channels can be normally received. Accordingly, a wide range of signal power levels (from low power to high power) can be received in excellent condition.

摘要： The invention may provide a receiver including a front-end block to provide a front-end gain on a radio-frequency input signal. The front-end block may include a mixer to convert the radio-frequency input signal to a baseband signal. The receiver also may include a wide-band peak detector coupled to the front-end block and a baseband block to provide a baseband gain on the baseband signal. An analog-to-digital converter may convert the baseband signal to a digital signal. The receiver may further include narrow-band peak detector coupled to an output of the analog-to-digital converter. An automatic gain control circuit may independently control the front-end gain and the baseband gain based on outputs from the wide-band peak detector and narrowband peak detector.

摘要： A receiving device performs log noise amplification on radio waves (desired waves and interfering waves), received with an antenna, to generate a received signal, converts the received signal into an intermediate frequency signal, converts the intermediate signal into a digital signal, filters out and demodulates a frequency band of a specific channel from the digital signal. Herein, a first received signal strength (RSSI 1) is detected from the digital signal, while a second received signal strength (RSSI 2) is detected from the digital signal of the specific channel. The intermediate frequency signal is amplified with a first gain which is calculated by way of the comparative judgment on the first receive signal strength and the allowable threshold. The digital signal of the specific channel is amplified with a second gain which is calculated by way of the comparative judgment on the level difference between the first received signal strength and the second received signal strength and the allowable threshold. When the level difference between the first received signal strength and the second received signal strength is smaller than the allowable threshold, the second gain is set to a multiplying factor 1 via multiplication scaling upon determining the nonexistence of interfering waves. Thus, it is possible to reliably receive desired waves, close to the minimum sensitivity, in environments undergoing strong interfering waves, thus demodulating desired waves with an appropriate level.

摘要： The present invention relates to a signal processing apparatus and a system and a method for automatic gain control using the same. It is possible to improve operation characteristics of a receiver in a strong electric field or a weak electric field by providing a signal processing apparatus including: a frequency sweeping unit for outputting a signal (S) for sweeping each channel frequency within a certain interval through a receiver; a signal level detecting unit for detecting a signal level of each channel by reading a gain value set when sweeping each channel frequency from the receiver; and a take-over point (TOP) adjusting unit for changing a TOP value of the receiver according to the detected signal level of each channel, and a system and a method for automatic gain control using the same.

摘要： A device and method of fast automatic gain control in quadrature receivers are disclosed. The AGC activity between the I and Q branches is split where in one branch the receive chain is in a certain gain state and in the other branch the receive chain is in another possible gain state, resulting in a significant shortening of the AGC duration of any IQ receiver.
