Noncoherent sequence detection receiver for Bluetooth systems

Noncoherent Sequence Detection: a New Perspective in Receiver Design

| In typical bandpass transmission systems, data detection must be performed in the absence of a phase reference. Noncoherent sequence detection represents the optimal solution of this problem, in the sense that it minimizes the probability of erroneously detecting the information sequence. This paper adopts this viewpoint and describes a class of recently-proposed approximate noncoherent seque...

Noncoherent receiver designs for ultra-wideband systems

Noncoherent sequence detection

In this paper, new noncoherent sequence detection algorithms for combined demodulation and decoding of coded linear modulations transmitted over additive white Gaussian noise channels, possibly affected by intersymbol interference, are presented. Optimal sequence detection in the presence of a random rotation of the signal phase, assumed to be constant during the entire transmission, requires a...

Noncoherent LMS algorithm for noncoherent sequence estimation

In this paper, a novel noncoherent adaptive algorithm for channel estimation is introduced. The proposed noncoherent least–mean–square (NC–LMS) algorithm can be combined easily with noncoherent sequence estimation (NSE) for M–ary differential phase–shift keying (MDPSK) signals transmitted over intersymbol interference (ISI) channels. For zero frequency offset the convergence speed and the stead...

Noncoherent sequence detection of continuous phase modulations

In this paper, noncoherent sequence detection, proposed in a companion paper [1] by Colavolpe and Raheli, is extended to the case of continuous phase modulations (CPM’s). The results in the companion paper on linear modulations with intersymbol interference (ISI) are used here because a CPM signal is mathematically equivalent to a sum of ISI-affected linearly modulated components, according to ...
