Patent ID: 8411800

Claim:
A Transmission Parameter Signaling (TPS) decoder, for a Digital Video Broadcasting-Terrestrial (DVB-T) television system, comprising: an input signal estimator, for receiving a plurality of frequency-domain input signals and a plurality of channel measure signals to produce a plurality of estimated input signals, wherein the frequency-domain input signals correspond to TPS signals from a frame and the estimated input signals produced by the input signal estimator are expressed as: EST q , m = ∑ l = 2 ⁢ d l q ⁢ ∑ k ⁢ b k · Re ⁢ { y l , k m · ( H ^ l , k ) * } , where EST q,m indicates the estimated input signals, Y l,k m indicates the frequency domain input signals, Ĥ l,k indicates the channel measure signals, b k =a 1 m , and d l q = ∏ i = 2 l ⁢ ⁢ a i q in which a k q indicates vector parts corresponding to the frequency domain input signals in transmission, and q=2 0 , . . . , 2 67 ; a masking device, connected to the input signal estimator, for performing a masking operation on the estimated input signals to produce a plurality of masking signals; a vector index determinator, connected to the masking device, for determining a vector index corresponding to the frequency-domain input signals according to the masking signals; and a lookup table device connected to the vector index determinator for producing a codeword according to the vector index.
