The cable TV (CATV) network is an ideal backbone for PCS due to its prevalent and broadcast nature. This significantly reduces the implementation costs and the handoff overheads. This paper proposes two architectures for the CATVbased PCS system. In the first architecture, each base station is equipped with multiple fixed receivers to provide fast and seamless handoffs for mobile users. Neverth...

This article presents a non-data-aided adaptive symbol timing offset correction algorithm to enhance the equalization performance in the presence of long delay spread multipath channel. The optimal timing phase offset in the presence of multipath channels is the one jointly optimized with the receiver equalizer. The jointly optimized timing phase offset with a given fixed length equalizer shoul...

A low-power high-speed optical receiver in 28nm CMOS is presented. The design features a novel architecture combining a low-bandwidth TIA front-end, double-sampling technique and dynamic offset modulation. The low-bandwidth TIA increases receiver’s sensitivity while adding minimal power overhead. Functionality of the receiver was validated and the design is compared with a conventional 3-stage ...

Realization of all-digital baseband receiver processing for multi-Gigabit communication requires analog-to-digital converters (ADCs) of sufficient rate and output resolution. A promising architecture for this purpose is the time-interleaved ADC (TI-ADC), in which L “sub-ADCs” are employed in parallel. However, the gain, timing and voltage-offset mismatches between the sub-ADCs, if left uncompen...

27 Abstract— In this paper, simulation and analysis of phase noise distortion in radio frequency (RF) transceiver of Wireless Local Area Network (WLAN) bridge system are presented. It is focused on the oscillator in RF transmitter and RF receiver in the transceiver. The effect of phase noise on the constellation error of RF transmitter and the receiver sensitivity of RF receiver is analysed bas...

Capability to combat channel fading and easy implementation have made the pilot symbol assisted modulation (PSAM) of practical interest in mobile communications. However, the operation in burst mode for multiple access purpose has sitill been a missing part from previous research. This work first examines the burst design problem associated with pilot symbol allocation in a frequency flat fadin...

The purpose of this paper is analysis the Signal To Noise Ratio (SNR) by changing the CFO. Frequency offset has been recognized as a major disadvantage of OFDM. The OFDM systems are sensitive to the frequency synchronization errors in form of Carrier Frequency Offset (CFO), because it can cause the Inter Carrier Interference (ICI) which can lead to the frequency mismatched in transmitter and re...

In this paper, an arrayed OFDM-CDMA system is modelled and studied in a frequency-selective environment. A blind near-far resistent channel estimator is devised which provides the joint angle, delay, and channel frequency offset (CFO) as well as the complex fading coefficients estimation. With the estimator integrated as the front-end, a subspace-based zero forcing receiver is used for frequenc...

Composite Binary Offset Carrier (CBOC) modulation is currently proposed for future Open Service (OS) Galileo signals in E1 frequency band. CBOC consists of a weighted sum or difference of two sine Binary Offset Carrier (BOC) waveforms: a sine BOC(1,1) and a sine BOC(6,1) component. The transmitted OS signal has both data and pilot channels. Data and pilot channels use slightly different modulat...
