摘要： A QRD-M decomposition includes a first and a sequential second stage, at least. In the first stage, M branches are selected from among more than M branches entering the first stage as survive branches from which multiple decompositions are calculated. In the second stage, more than M branches are selected from among those branches entering the second stage as survive branches from which multiple decompositions are calculated. The symbol of the received signal is decided from a branch that is a survive branch of both the first and second stages. The second stage may be within a window that may include additional stages at which the pruning decision down to M survive branches is delayed. One or more windows may be used in a single QRD-M decomposition. In an embodiment, all branches entering the second stage are survive branches. It is shown that the marginal increased computational load increases accuracy.

摘要： The present invention relates to a method, receiving apparatus and computer program product for subblock-wise frequency domain equalization, wherein a data block of a received signal is segmented into at least two subblocks at a receiving end of a transmission channel. The subblocks are then equalized separately in the frequency domain, and equalized subblocks are combined to obtain an equalized signal. Thereby, Doppler induced interference can be suppressed to achieve enhanced robustness to high Doppler and compensate performance degradation due to rapidly varying channels.

摘要： A method and transceiver for wireless multicarrier communications. At the transmitter side, conventional OFDM symbols, after inverse fast Fourier Transform, are scrambled in time domain and then guard-interval (GI) inserted, up-converted at the carrier frequency for transmission. At the receiver side, after GI removal and frequency domain channel equalization, the received signal is transformed into time-domain by inverse fast Fourier Transform. The time-domain equalized signal is descrambled in time domain and then transformed back to the frequency domain before it is rate-matched, demodulated and decoded. This time-domain scrambling and descrambling method can be used in a wireless OFDM system such as WLAN, cellular OFDM, and MC-CDMA.

摘要： In a multiple-input multiple-output (MIMO) system, a high-rate data transmission is achieved by dividing an original data stream into several parallel data substreams, each of which is transmitted from a corresponding transmit antenna (spatial multiplexing) and received by multiple receive antennas. The number of spatial streams depends on the number of antennas. In a receiver, a search-tree based QR Decomposition-M (QRD-M) algorithm is used. According to the invention, multiple spatial signal streams received from a MIMO channel are pre-ordered (60, 62) based on modulation alphabets of said received spatial signal streams prior to performing a QRD-M detection (66).
