    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: This invention describes a blind speech user interference cancellation receiver for a high-speed downlink packet access (HSDPA). The key component of the blind SUIC receiver is a joint estimation on hard-decision HSDPA signals and soft-decision interfering speech user (ISU) signals with a full Walsh transform correlator used instead of the conventional RAKER, where the outputs are separated into two parts: the desired HSDPA signal with known spreading codes and the ISU signal with unknown spreading codes. The invention further describes a multistage processing for reaching a targeted convergence rate or a desired bit-error-rate for a received signal involving a hard-decision on the desired HSDPA signal and a soft-decision on the ISU signal.

    摘要: The invention relates to a method and a system for digital signal transmission. In this method, a signal is encoded in order to minimize transmission errors on a transmission channel, and the encoded signal is sent through at least two base stations. A user equipment then receives the encoded signal and the coding of the received signal is decoded. The method is in accordance with the invention characterized in that the encoded signal is divided into separate signal parts having at least partly different contents. Then a specific signal part is indicated for each base station, and the base stations send their specific signal parts. In reception, the information in the received signal parts is combined.

    摘要: There is provided a mechanism for controlling a transmission of data in a fragmentation transmission mode. When fragments are transmitted in a fragmentation transmission mode, it is determined whether the fragment frame is received successfully or whether an acknowledgment message for confirming a successful transmission of the fragment frame is received. In case the acknowledgment for the successful transmission of the one fragment frame is not received, or the fragment is frame is not successfully received, the fragmentation transmission mode is maintained and a retransmission of the fragment frame is initiated.
