Patent ID: 8548081

Claim:
A method for diversity combining in an orthogonal frequency division multiple access (OFDMA) system, comprising: performing repetition diversity equalization and combining with respect to received OFDMA signals; and performing receiver antenna diversity equalization and combining with respect to the received OFDMA signals, wherein the repetition diversity equalization and combining and the receiver antenna diversity equalization and combining are performed in accordance with a maximum ratio combining (MRC) scheme, and wherein the repetition diversity equalization and combining and the receiver antenna diversity equalization and combining are performed as R e ⁡ ( z , k ) = ∑ c = 1 N c ⁢ ∑ s = ( z - 1 ) ⁢ R + 1 ( z - 1 ) ⁢ R + R ⁢ R s ⁡ ( c , s , k ) ⁢ H s ⁡ ( c , s , k ) * ∑ c = 1 N c ⁢ ∑ s = ( z - 1 ) ⁢ R + 1 ( z - 1 ) ⁢ R + R ⁢  H s ⁡ ( c , s , k )  2 , wherein R s ( ) indicates the received OFDMA signals, wherein H s ( ) indicates channel estimates, wherein c is a communication channel index, wherein z is a slot index prior to repetition coding, wherein s is a slot index after repetition coding, and wherein k is a subcarrier index.
