Abstract: Apparatus, and an associated method, for downloading an operational parameter to a mobile station. The operational parameter is stored at a server operated by an operator of a communication system in which the mobile station is operable. When the parameter is to be downloaded to the mobile station, the server instructs a SMS, or other data message, service center to generate a data message to be delivered to the mobile station, instructing the mobile station to initiate a data call connection with the server. When a data call connection is formed, the operational parameter is downloaded to the mobile station, thereafter to be used by the mobile station in subsequent communication operations in the communication system.

Abstract: A direct conversion receiver uses an algorithm implemented by a DSP to cancel residual DC offsets during demodulation of a GMSK modulated signal. The algorithm exploits the characteristics of GMSK modulation by determining the. modulation extremes within sampled I/Q signals and calculates the DC offset as the mean of the extremes. This offset is used to weight a declining exponential function which is subtracted from the original signal samples to achieve compensation.

Abstract: A method for decoding video data blocks using variable length codes, comprising transforming information about the spatial frequency distribution of a video data block into pixel values. Prior to said transformation, a first reference value (Xref) representing the abruptness of variations in information about spatial frequency distribution within the block is generated, after said transformation, a second reference value (?) representing the abruptness of variation in certain information between the block and at least one previously transformed video data block is generated. The first reference value (Xref) is compared to a first threshold value (TH1) and the second reference value (?) to a second threshold value (TH2); and as a response to either of the first (Xref) and second reference values (?) being greater than the first (TH1) and respectively the second threshold value (TH2), an error in the block is detected.
