Method and system for generating a received signal strength indicator (RSSI) value that corresponds to a radio frequency (RF) signal

A system for generating a received signal strength indicator (RSSI) value that corresponds to a radio frequency (RF) signal, the system comprising:

• an automatic gain control (AGC) device configured to obtain an attenuation factor code in response to applying an AGC operation to the RF signal;
• an analog-to-digital converter (ADC) device configured to obtain an ADC code in response to applying an ADC operation to a signal that results from the AGC operation;
• and
• an RSSI device configured to combine the attenuation factor code and the ADC code to generate an RSSI value, wherein the RSSI device is further configured to perform a bit shift operation on the attenuation factor code and the ADC code, and wherein the number of bits of the RSSI value is equal to the sum of the number of bits of the attenuation factor code and the number of bits of the ADC code.

A method for generating a received signal strength indicator (RSSI) value that corresponds to a radio frequency (RF) signal, the method comprising:

• obtaining an attenuation factor code in response to applying an automatic gain control (AGC) operation to the RF signal;
• obtaining an analog-to-digital converter (ADC) code in response to applying an ADC operation to a signal that results from the AGC operation;
• appending the attenuation factor code to the most significant bit (MSB) of the ADC code to generate an RSSI value;
• and
• placing the RSSI value into an RSSI lookup table.
