A polar-coded transmission (PCT) scheme with joint channel estimation and decoding is proposed for channels unknown state information (CSI). The CSI estimated via successive cancellation (SC) the constraints imposed by frozen bits. SC list an outer code improves performance, including resolving a phase ambiguity when using quadrature phase-shift keying (QPSK) Gray labeling. Simulations 5G polar...

This paper presents the integrated circuit design of an ultra-wideband (UWB) transceiver for a wireless endoscope that enables real-time diagnosis with high resolution images. The implemented UWB transceiver is a non-coherent transmit reference (TR) architecture with differential binary phase shift Keying (DBPSK) modulation. All-digital pulse generator (PG) and merged radio frequency (RF) front...

© 2010 Bin Shen et al. 333 This letter proposes a non-coherent blind time-of-arrival (TOA) estimation scheme for impulse radio ultra-wideband systems. The TOA estimation is performed in two consecutive phases: the Rayleigh-quotient theorem-based coarse-signal acquisition (CSA) and the iterative-threshold-test-based fine time estimation (FTE). The proposed scheme serves in a blind manner without...

This chapter provides an overview of the techniques of radio astronomy. This study began in 1931 with Jansky’s discovery of emission from the cosmos, but the period of rapid progress began fifteen years later. From then to the present, the wavelength range expanded from a few meters to the sub-millimeters, the angular resolution increased from degrees to finer than milli arc seconds and the rec...

In the paper, the preamble structure of IMT-2000 SW-CDMA air radio interface is considered in the evaluation of the performance of different post detection integration techniques for code acquisition in the return link of a satellite W-CDMA system. In particular, non-coherent post detection integration (NCPDI) and two different options of differential post detection integration (DPDI) technique...

In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility. However, because of the non-coherent measurements and strong absorption of X-band radio waves...
