摘要： A baseband processing module for use within a Radio Frequency (RF) transceiver includes a downlink/uplink interface, TX processing components, a processor, memory, RX processing components, and a turbo decoding module. The RX processing components receive a baseband RX signal from the RF front end, produce a set of IR samples from the baseband RX signal, and transfer the set of IR samples to the memory. The turbo decoding module receives a set of IR samples from the memory, forms a turbo code word from the set of IR samples, turbo decodes the turbo code word to produce inbound data, and outputs the inbound data to the downlink/uplink interface. The turbo decoding module performs metric normalization based upon a chosen metric, performs de-rate matching on the set of IR samples, performs error detection operations, and extracts information from a MAC packet that it produces.

摘要： Certain aspects of a method and system for dynamically adjusting intermediate frequency (IF) and filtering in microwave circuits may include generating one or more intermediate frequency (IF) signals from one or more baseband signals and/or one or more radio frequency (RF) signals. The generated one or more IF signals may be filtered to avoid detected interference and/or detected noise from out-of-band radio sources. The frequency of the generated one or more IF signals may vary depending on the detected interference and/or detected noise. The filtering of the generated one or more IF signals may be adjusted based on the variation in the frequency of the generated one or more IF signals. The one or more RF signals may be down-converted to generate the one or more IF signals. The generated IF signals may be further down-converted and dynamically filtered to generate the desired baseband signals.

摘要： A miniaturized dual-balanced mixer circuit based on a double spiral layout architecture is proposed, which is designed for use to provide a frequency mixing function for millimeter wave (MMW) signals, and which features a downsized circuit layout architecture that allows IC implementation to be more miniaturized than the conventional star-type dual-balanced mixer (DBM). The proposed miniaturized dual-balanced mixer circuit is distinguished from the conventional star-type DBM particularly in the use of a double spiral layout architecture for the layout of two balun circuit units. This feature allows the required layout area to be only about 15% of that of the conventional star-type DBM.
