Abstract: A high-speed search method in a speech encoder using an order character of LSP (Line Spectrum Pair) parameters in an LSP parameter quantizer using SVQ (Split Vector Quantization) used in a low-speed transmission speech encoder, includes the steps of rearranging a codebook according to an element value of a reference row for determining a range of code vectors to be searched; and determining a search range by using an order character between a given target vector and an arranged code vector to obtain an optimal code vector. The method gives effects of reducing computational complexity required to search the codebook without signal distortion in quantizing the LSP parameters of the speech encoder using SVQ, and reducing computational complexity without loss of tone quality in G.729 fixed codebook search by performing candidate selection and search on the basis of the correlation value size of the pulse position index.

Abstract: Disclosed herein are a terrestrial digital multimedia broadcasting (DMB) tuner of a low intermediate frequency (IF) structure which is applied to a mobile communication terminal, such as a mobile phone, and an image rejection mixer applied thereto. In order to improve inter-channel attenuation characteristics, the image rejection mixer locates an oscillation frequency above or beneath the frequency of a target signal to include an image signal of the target signal in a terrestrial DMB band, mixes a radio frequency (RF) signal with the oscillation frequency, and outputs the resulting IF signals to a polyphase filter in a selected arrangement. Because the image signal of the target signal is included in the terrestrial DMB band, the image rejection mixer can satisfy the inter-channel attenuation characteristics without a troublesome or complex design.

Abstract: Disclosed herein is a receiver for down-conversion of a dual band. The receiver can down convert radio frequency signals of two different bands into a desired IF signal using only one voltage controlled oscillator (VCO), by dividing the output of the VCO into a predetermined ratio with a divider. The VCO outputs a desired oscillating frequency for conversion of the first-band RF signal into the IF signal, and the divider divides the desired oscillating frequency in a predetermined ratio to output a frequency for conversion of the second-band RF signal into the IF signal. Thus, the receiver can be formed on one silicon substrate.
