Implementation of a Bandwidth-Efficient M-FSK Demodulator for Powerline Communications
White Paper Signal demodulation is performed in a direct mode, by undersampling and analyzing consecutive triplets of signal samples. In this paper, an implementation of a bandwidth - efficient M-ary frequency-shift keying (M-FSK)... [11 Jul 2008]
Turbo Demodulation of Zero-Padded OFDM Transmissions
White Paper This paper has extended the turbo-demodulation procedure to ZP-OFDM by accounting for the noise color introduced by the linear equalization. Simulations have shown that iterative demodulation increases... [10 Apr 2008]
Motorola Semiconductor Products Sector: SPW Tools Play a Significant Role in OFDM DVB-T Chip Development for Set Top Boxes

Compensation of IQ Imbalance in OFDM Systems
White Paper However, this implies IQ demodulation at RF, which therefore cannot be done digitally and thus introduces IQ mismatch. Today a lot of attention is spent on developing inexpensive OFDM receivers. Especially, zero-IF... [10 Apr 2008]
Software Defined Radio
White Paper SDR technology facilitates implementation of some of the functional modules in a radio system such as modulation/demodulation, signal generation, coding and link-layer protocols in software. A radio system built using... [25 Jun 2007]
Performance Analysis and Design Optimization of LDPC-Coded MIMO OFDM Systems
White Paper In particular, the optimization is done for various MIMO OFDM system configurations, which include a different number of antennas, different channel models, and different demodulation schemes; the optimized performance... [26 Apr 2007]
Optimum Nyquist Windowing in OFDM Receivers
White Paper Conventional orthogonal frequency-division multiplexing receivers disregard the guard interval in channels with small dispersion even though its unconsumed portion can be exploited for improved demodulation by applying a... [14 Apr 2007]
Blind and Semiblind Spatio-Temporal Diversity for OFDM Systems
White Paper They are usually applied in the frequency domain, after the FFT demodulation. Adaptive antenna arrays can be used to improve the performance of Orthogonal Frequency Division Multiplexing systems. In this paper, the... [14 Apr 2007]
A Simple Space-Frequency Coding Scheme With Cyclic Delay Diversity for OFDM
White Paper On each antenna a shifted version of the signal is sent which enables the receiver to apply optimum demodulation. Cyclic Delay Diversity (CDD) is a simple approach to increase the frequency selectivity of the channel in... [13 Apr 2007]
Pilot-Tone Based ZP-OFDM Demodulation for an Underwater Acoustic Channel
White Paper Existing coherent underwater acoustic communication systems rely on single carrier transmission and adaptive decision feedback equalization to deal with time-varying and highly dispersive UnderWater Acoustic (UWA) channels. [11 Apr 2007]
On the Throughput of Bluetooth Data Transmissions
While not attainable in practice due to the IS1 caused by Gaussian pulse shaping, these curves can serve as a benchmark for actual demodulation techniques used by Bluetooth devices. The throughput of the six Bluetooth... [10 Nov 2005]
