Patent ID: 7729663

Claim:
A method of calculating Signal to Noise Ratio (SNR) comprising: generating a first power value based on frequency domain subcarriers corresponding to a received signal using a first equation, wherein the first equation comprises: P n = ( ∑ k = 1 ⁢ : ⁢ 2 ⁢ : ⁢ 99 ⁢  X k  2 + ∑ k = 155 ⁢ : ⁢ 2 ⁢ : ⁢ 253 ⁢  X k  2 ) ; generating a second power value based on the frequency domain subcarriers using a second equation, wherein the second equation comprises: P s = ( ∑ k = 2 ⁢ : ⁢ 2 ⁢ : ⁢ 100 ⁢  X k  2 + ∑ k = 156 ⁢ : ⁢ 2 ⁢ : ⁢ 254 ⁢  X k  2 ) - P n ; calculating an SNR value of the received signal based, at least in part, on a ratio between the first power value and the second power value; and utilizing the SNR value to modify operational parameters.
