Claim:
A receiver comprising: a receive antenna that receives sequences, wherein a first received sequence and a second received sequence are represented by vectors Y i and Y i+1 where [ Y i Y _ i + 1 ] = [ Λ 1 - Λ 2 Λ 2 * Λ 1 * ] ⁡ [ X ^ i X _ ^ i + 1 ] + [ V i V _ i + 1 ] Wherein Λ 1 is an impulse response associated with a first transmit channel, wherein Λ 2 * is an impulse response associated with a second transmit channel, wherein Λ 1 * and Λ 2 * respectively represent complex conjugates of Λ 1 and Λ 2 , and wherein [ V i V i + 1 ] represents noise associated with the first and the second transmit channels, wherein {circumflex over (X)} i corresponds to an estimate of X 1 , and wherein {circumflex over (X)} i+1 corresponds to an estimate of X i+1 ; and a processor that generates complex conjugates of sequences received during a first time slot, to process sequences received during a second time slot following the first time slot without generating complex conjugates, and to combine the complex conjugates of sequences received during the first time slot and the sequences received during the second time slot to generate decoded symbols, wherein the processor generates decoded equalized vectors Z i , and Z i+1 from Y i and Y i+1 defined by: [ Z i Z i + 1 ] ⁢ • ⁢ D ~ - 1 · [ Λ 1 * ⁢ Y i + Λ 2 ⁢ Y _ i + 1 - Λ 2 * ⁢ Y i + Λ 1 ⁢ Y _ i + 1 ] where D ~ = D + 1 ρ ⁢ I , wherein I is an identity matrix, wherein D=Λ 1 Λ 1 *+Λ 2 Λ 2 * and wherein ρ represents a signal-to-noise ratio.
