    Abstract: In one disclosed embodiment, data information is stored in a buffer in a transmitter. The data information is transmitted on a shared channel and control information for recovering the associated data information is transmitted on a dedicated channel. The shared and dedicated channels can be, for example, different portions of the frequency band. The control information can include a spreading factor used to spread the data at the transmitter. For example, the spreading factor can be the length of the Walsh function orthogonal coding used to spread the data. The control information is received over the dedicated channel before the associated data information is received over the shared channel. The control information is then used to recover the associated data information. For example, knowing the spreading factor from the control information, the correct Walsh function can be selected to de-spread, i.e. to Walsh de-cover, the data information.

    Abstract: A CDMA communication system includes a signal processor which encodes voice and nonvoice signals into data at various rates, e.g. data rates of 8 kbps, 16 kbps, 32 kbps, or 64 kbps as I and Q signals. The signal processor selects a specific data rate depending upon the type of signal, or in response to a set data rate. When the signal is received and demodulated, the baseband signal is at the chip level. Both the I and Q components of the signal are despread using the conjugate of the pn sequence used during spreading, returning the signal to the symbol level. Carrier offset correction is performed at the symbol level. A lower overall processing speed is therefore required.

    Abstract: The present disclosure relates to a communication technique for converging IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems and to a system therefor. The present disclosure can be applied to intelligent services (e.g. smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The method for data decoding by a terminal in a wireless communication system according to the present disclosure comprises the steps of: receiving subframes on the basis of a configuration; obtaining at least one channel phase value on the basis of available subframes, which are configured to transmit identical downlink data, among the received subframes; correcting the other channel phase value(s) with any one of said at least one obtained channel phase value as a reference value; and decoding the downlink data by means of the reference value and the corrected channel phase value(s).

    Abstract: The present invention is an apparatus for reducing transmission errors by a user equipment (UE) when transmitting a communication signal. An RF communication signal is received at the UE and analyzed for errors. A correction signal is then generated based upon the analysis. Prior to transmission of the communication signal from the UE, the communication signal is corrected using the correction signal.
