Patent ID: 7646832

Claim:
An apparatus, comprising: a sampler configured to sample a received signal carrying a stream of symbols to form samples being a first set of actual samples; an interpolator configured to interpolate between the samples of the first set of actual samples to form a second set of interpolated samples; and a symbol recovery unit configured to process the first set of actual samples and the second set of interpolated samples to form an estimate of the stream of symbols of the received signal by performing temporal whitening on signals derived from the first set of actual samples and the second set of interpolated samples: wherein the symbol recovery unit comprises a demodulator configured to demodulate the first set of actual samples and the second set of interpolated samples to produce first and second demodulated data sets, respectively, and a channel estimator configured to perform a channel estimation on the first and second demodulated data sets to form first and second channel estimation data sets, respectively, the first and second channel estimation data sets being the signals derived from the first set of actual samples and the second set of interpolated samples.
