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 invention is a method and 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.

Abstract: PROBLEM TO BE SOLVED: To provide a communication system which pre-corrects a signal for error generated when transmitting a communication signal in a digital Code-Division Multiple Access (CDMA) communication system. SOLUTION: A digital spread spectrum communication system calculates phase and frequency error on a received signal from a communicating entity during a communication and pre-corrects a signal for phase and frequency error prior to transmission to that entity.

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).
