摘要： An interleaver and method of interleaving operate on data represented in a sequence of symbols to produce an interleaved sequence of symbols. The interleaver performs intra-block and inter-block permutations on the sequence of symbols. An encoder and method of encoding operate on data represented in a source sequence of symbols. The source sequence of symbols is encoded into a first sequence of codewords and interleaved using intra-block and inter-block permutations to produce a sequence of interleaved symbols. The sequence of interleaved symbols is encoded into a second sequence of codewords. A decoder and method of decoding operate on data represented in a sequence of received symbols. The sequence of received symbols comprises a formatted copy of the source sequence of symbols and the first and the second sequence of codewords.

摘要： A circuit for down-converting an RF signal to a baseband signal includes a trans-admittance amplifier adapted to receive the RF signal and generate in response a pair of differential current signals. The circuit further includes a trans-impedance amplifier having at least four mixers and at least four linear amplifiers. The four mixers frequency down-convert the pair of differential current signals to generate four pairs of differential baseband current signals, wherein each pair of the differential baseband current signals has a different phase and is associated with each of the linear amplifiers. Additionally, the circuit includes a summing block that generates an in-phase signal using a first weighted sum of the four different baseband current signals and a quadrature signal using a second weighted sum of the four different baseband current signals. The circuit further includes an analog-to-digital converter for converting the in-phase and quadrature signals to respective digital representations.
