Method and apparatus for signal-to-noise ratio (SNR) estimation

An apparatus, comprising:

• a memory;
• a processor;
• and
• a receiver configured to:
• receive a signal sequence and a noise sequence,
• determine a first sum of absolute values of a receive power of the signal sequence, wherein the signal sequence contains both signal and noise,
• determine a second sum of absolute values of a noise power of the noise sequence, and
• determine a signal-to-noise ratio (SNR) based on bias compensation,
• wherein the bias compensation includes summing a first decibel term and a second decibel term,
• wherein the first decibel term is based on converting a result of a summation of the first sum of absolute values and the second sum of absolute values into a decibel domain, and
• wherein the second decibel term is based on converting a result of a subtraction of the second sum of absolute values from the first sum of absolute values into the decibel domain.

A method of manufacturing a processor, comprising:

• forming the processor as part of a wafer or package that includes at least one other processor, wherein the processor is configured to receive a signal sequence and a noise sequence, determine a first sum of absolute values of a receive power of the signal sequence, wherein the signal sequence contains both signal and noise, determine a second sum of absolute values of a noise power of the noise sequence, and determine a signal-to-noise ratio (SNR) based on bias compensation,
• wherein the bias compensation includes summing a first decibel term and a second decibel term,
• wherein the first decibel term is based on converting a result of a summation of the first sum of absolute values and the second sum of absolute values into a decibel domain, and
• wherein the second decibel term is based on converting a result of a subtraction of the second sum of absolute values from the first sum of absolute values into the decibel domain.

A method of constructing an integrated circuit, comprising:

• generating a mask layout for a set of features for a layer of the integrated circuit, wherein the mask layout includes standard cell library macros for one or more circuit features that include a memory, a processor, and a receiver configured to receive a signal sequence and a noise sequence, determine a first sum of absolute values of a receive power of the signal sequence, wherein the signal sequence contains both signal and noise, determine a second sum of absolute values of a noise power of the noise sequence, and determine a signal-to-noise ratio (SNR) based on bias compensation,
• wherein the bias compensation includes summing a first decibel term and a second decibel term,
• wherein the first decibel term is based on converting a result of a summation of the first sum of absolute values and the second sum of absolute values into a decibel domain, and
• wherein the second decibel term is based on converting a result of a subtraction of the second sum of absolute values from the first sum of absolute values into the decibel domain.
