Abstract: A frequency modulated continuous wave (FMCW) radar system that includes a transceiver coupled to an analog to digital converter (ADC), and a digital signal processor (DSP) coupled to the ADC. The transceiver is configured to transmit a plurality of FMCW chirps, receive a plurality of reflected FMCW chirps, and mix the reflected FMCW chirps with at least one of the FMCW chirps to generate a plurality of beat signals. The reflected FMCW chirps are the FMCW chirps after being reflected off of a target object. The ADC is configured to convert the beat signals into a plurality of digital chirps. The DSP is configured to receive the digital chirps and quantify a relative velocity of the target object as compared to a velocity of the FMCW radar system by removing an effect of a range to the target object from a two dimensional range Doppler processing signal.

Abstract: A method for wireless backhaul communication comprising receiving, by a wireless backhaul transmitter, a data stream in a bit format and generating, by the wireless backhaul transmitter using a single-carrier block transmission scheme, a radio frame to include a plurality of physical data channel (PDCH) blocks, a pilot signal (PS) block and a physical control channel (PCCH) block with each block type pre-appended with a cyclic prefix (CP). A length of the PS block in symbols, a length of the PCCH block in symbols and a length of the PDCH block in symbols is determined by a frequency band, a bandwidth, and a channel condition. The wireless backhaul transmitter then transmits the radio frame.
