Noncoherent communication receivers (differential-detectors) have simple design, however, they always incur bit error rate (BER) performance loss up to 3dB compared to coherent receivers. In this paper, a differential-detector is proposed for impulse radio ultra wideband (IR-UWB) communication systems. The system employs bit-level differential phase shift keying (DPSK) combined with code division (CD) for IR-UWB signals to support multiple-access (MA). It is analyzed under additive white Gaussian noise (AWGN) corrupted by multiple-access interference (MAI) channel. Its BER performance is compared against a reference coherent receiver using Monte-Carlo simulation method. A closed form expression for its average probability of error is derived analytically. Simulation results and theoretical analysis confirm the applicability of the proposed differential-detector for IR-UWB communication systems.

“…The randomness of the used PN code sequences with the existence of more than one active-user concurrently in the system permits the approximation of MAI terms, am n in (11) and bm n in (19) as Gaussian random processes [12]. Therefore, the variable statistic a α can be expressed as n n n = × .…”

“…The coherent schemes correlate the received signal with a well-designed template generated locally or from the received training signal. Typically, one example is Rakereceiver structures [8], but unfortunately, despite their high accuracies, they are not suited for low-complexity and low-power applications. Because of the capturing enough signal energy from the large number of paths and the computational load from estimating the gains and delays of the paths, the acquisition time is especially long and the implementation is very complex [9].…”

The timing acquisition of IR-UWB system with very short pulse is difficult to implement due to high sampling rate and high resolution ADC. In this paper, a new two-step timing acquisition method combining energy detection (ED) scheme with the monobit digital receiver is proposed. The usage of the monobit digital receiver, with the comparator instead of high resolution ADC, can reduce the complexity greatly; using the ED scheme to cut down the received data region, the computational load of digital signal processing (DSP) part can be decreased significantly. The acquisition probability of each step is analyzed in this paper. The performance of this approach is also demonstrated comparing with separate monobit and ED methods via simulation.

“…On the other hand, the non-coherent reception can be implemented with low complexity, because strict channel estimation is not required. The energy detection is one of the non-coherent detection schemes with low complexity [3]. However, the energy detection system has expense of some performance degradation.…”

This paper discusses a multi-user access technique for Ultra-wideband Impulse Radio (UWB-IR) system in energy detection receiver. The UWB-IR system is modulated by OnOff shift Keying (OOK). As multi-users access scheme, the Code Division Multiple Access (CDMA) using the Optical Orthogonal Code (OOC) sequence is adopted. The integral interval and the sample energy threshold value are optimized to improve the Bit Error Rate (BER) performance. The BER performances of proposed scheme are evaluated and compared with conventional energy detection receiver in the low data rate PAN (Personal Area Network) channel. The effect of inter-user interference is improved by using proposed optimization technique.
