On Pilot Symbol Aided Channel Estimation for Time Varying Rayleigh Fading Channels
نویسندگان
چکیده
This paper considers the performance of pilot symbol aided channel estimation by investigating the achievable information rate in a fading channel. The channel is modeled as a time varying Rayleigh fading process whose dynamics are characterized by the normalized fading rate. The optimal fractions of bandwidth and power allocated to the pilot symbols are determined and presented in terms of the signal to noise ratio (SNR) and fading rate.

Performance analysis of pilot symbol aided QAM for Rayleigh fading channels
Abstract—In this paper we derive upper bounds on the symbol error probability for a communication system that sends quadrature amplitude modulated data over a frequency-flat Rayleigh fading channel. We first derive simple error bounds in terms of a key parameter, namely, the channel estimation error variance. We move on to derive expressions for the this parameter for a pilot symbol assisted ch...
متن کاملPilot-Symbol-Aided 16PSK and 16QAM for Digital Land Mobile Radio Systems
The paper proposes a novel pilot-symbol-aided (PSA) technique for fading compensation of digital signals in the mobile environments. In a PSA system, the data sequence at the transmitter is divided into frames of data. A pilot symbol from a known pseudoradom-symbol sequence is inserted periodically into a frame of data symbol for transmission. In a conventional PSA-receiver, these pilot symbols...
متن کاملBit Error Probability for Pilot-Symbol-Aided OFDM Channel Estimation in Doubly-Selective Channels
In this paper, we derive a closed-form expression for the Bit Error Probability (BEP) of an orthogonal frequencydivision multiplexing system that utilizes pilot-symbol-aided channel estimation. We assume Rayleigh fading, additive white Gaussian noise, and that the interpolation is linear but otherwise completely arbitrary. It is shown that the minimum mean squared error interpolation also minim...
متن کاملPilot symbol assisted BPSK on Rayleigh fading channels with diversity: performance analysis and parameter optimization
|In this paper, the loss due to imperfect channel estimation is derived for pilot symbol assisted BPSK on fading channels with diversity. The presented approach, which holds for both narrowband and spread spectrum communication, further provides an analytical optimization of pilot symbol spacing. The loss due to channel estimation is demonstrated to be low if the maximum Doppler frequency is si...
متن کاملBayesian Cramer-Rao bounds for complex gain parameters estimation of slowly varying Rayleigh channel in OFDM systems
This paper deals with on-line Bayesian Cramer-Rao (BCRB) lower bound for complex gains dynamic estimation of time-varying multi-path Rayleigh channels. We propose three novel lower bounds for 4QAM OFDM systems in case of negligible channel variation within one symbol, and assuming both channel delay and Doppler frequency related information. We derive the true BCRB for data-aided (DA) context a...
