The reception of a COFDM signal is analyzed here for the case where phase noise has been added to the signal, e.g. by a receiver local oscillator. Two effects are distinguished: common phase error (a rotation of the signal constellation) and inter-carrier interference (similar to additive Gaussian noise). It is shown that the amounts of these effects can be deduced from the spectrum of the phas...
The development of high-definition television (HDTV) in the United States has recently resulted in the establishment of a national standard for its coding and transmission. This standard dictates, among other specifications, certain limitations on the allowable resolution of transmitted HDTV signals. There are many of these allowable formats, permitting scene-dependent processing and encoding; ...
In this paper, we present a prototype transmitter and receiver with set partitioning (SP)-64 amplitude phase shift keying (APSK) coded modulation developed for expanding satellite transmission capacity. SP-multi-level is scheme that can improve noise immunity by properly combining scheme, bit allocation, error-correction codes. We designed SP-64APSK on the basis of channel capacity confirmed it...
Battery life-time is a critical issue for digital television (DVB) viewing on mobile phones. The number of quantization steps used in the analog-to-digital converter (ADC) is an important factor in the total power consumption of a DVB receiver. The OFDM signals require a large resolution of the ADC. We propose a digital post-processing method that allows reduction of the peak-to-average margin ...
High reliability of wireless communications is a rudimentary requirement for guaranteeing safe autonomous driving. This paper discusses the performance between cars within platoons, with application proposed database-supported successive interference cancellation (SIC) algorithm. By assumption, it utilizes knowledge on other existing interfering transmissions (such as pre-entered information di...
At a receiver terminal, true 3D video provides ability to watch views selected from a large number of available views. Such ability is needed for the forthcoming 3D video applications like free-view television, autostereoscopic displays etc. Delivery of many views through communication channels is a challenging problem that has to be solved in the near future. In this paper, we study delivery o...
The diversity of European television standards has been referred to more than once in this Review. From. the point of view of th~se concerned with T. V. transmission, the most important consequence of this lack of uniformity is that it necessitates the use of "line converters" in any international exchange of programmes. The receiver designer, on the other hand, is concerned with the demand cre...
A new method of co-channel interference rejection for digital television receivers is presented that uses a di erent rejection lter from the comb lter that was used in the prototype built by Zenith. This lter is optimized for rejection of co-channel NTSC interference in the presence of white noise and hence su ers a penalty of only 0.4 dB in AWGN as compared to 3.5 dB with the comb. The receive...
