Double trellis-coded CPM - Communications, 1988. ICC 88. Digital Technology - Spanning the Universe. Conference Record. IEEE
The method of multiple trellis-coded modulation is applied to continuous phase modulation (CPM). Especially double trellis-coded quaternary CPM schemes using convolutional codes with an effective rate 2/4 are considered. Tables of optimum codes and minimum Euclidean distances are given for several frequency impulses and numbers of trellis branches per symbol interval, which have to be processed...
متن کاملICI mitigation for mobile OFDM receivers - Communications, 2003. ICC '03. IEEE International Conference on
Orthogonal Frequency Division Multiplexing (OFDM) is robust against Inter-Symbol-Interference (ISI) due to the increase of the symbol duration. However, for mobile applications, channel variations during one OFDM symbol introduce Inter-Carrier-Interference (ICI), which degrades the performance. This gets more severe as mobile speed, carrier frequency or OFDM symbol duration increases. We introd...
متن کاملTurbo synchronization : an EM algorithm interpretation - Communications, 2003. ICC '03. IEEE International Conference on
This paper is devoted to turbo synchronization, that is to say the use of soft information to estimate parameters like carrier phase, frequency offset or timing within a turbo receiver. It is shown how maximum-likelihood estimation of those synchronization parameters can be implemented by means of the iterative expectation-maximization (EM) algorithm [1]. Then we show that the EM algorithm iter...
متن کاملDetection with particle filtering in BLAST systems - Communications, 2003. ICC '03. IEEE International Conference on
This work demonstrates the use of particle filtering for detection in BLAST systems. A novel dynamic state-space model (DSSM) is constructed for BLAST systems that is crucial for development of particle filtering algorithms. The proposed DSSM is based on QR decomposition and the output of the feedforward filter, and it evolves in space. The particle filtering solution does not suffer from error...
متن کاملSuperposition turbo TCM for multi-rate broadcast - Communications, 2003. ICC '03. IEEE International Conference on
Bergmans and Cover identified the capacity region of the Gaussian degraded broadcast channel, where different receivers observe the transmitted signal with different signal to noise ratios. This paper presents a superposition turbo coding scheme that performs within 1 dB of the capacity region boundary of the degraded broadcast channel at BER of 10−5. Performance is consistent over the entire u...
