چکیده

AbstmctBared on a Volterra-type channel model, we suggest a coded solution for compensating the nonlinear distortion of TDMA satellite waveforms. The resulting receiver for the coded system uses the iterated detection principle that iteratively equalizes the nonlinear channel and then decodes the equalized symbols. Computer simulation results show that signiflcant improvement over (conventional approach can be achieved.

Turbo equalization of nonlinear TDMA satellite signals

In this paper, we investigate a coded solution to compensate for the nonlinear distortion of TDMA satellite waveforms. Based on a Volterra-type channel model and the turbo principle, we present a turbo-like system that includes a simple rate-1 encoder at the transmit side in addition to a conventional channel encoder; the receive side iteratively equalizes the nonlinear channel effect and decod...

Frequency Domain Nulling Filter and Turbo Equalizer in Suppression of Interference for One-Cell Reused Single-Carrier TDMA Systems

This paper proposes a frequency domain nulling filter and Turbo equalizer to suppress interference in the uplink of one-cell reuse single-carrier time division multiple access (TDMA) systems. In the proposed system, the desired signal in a reference cell is interfered by interference signals including adjacent-channel interference (ACI), co-channel interference (CCI), and intersymbol interferen...

SCCC Turbo Equalizer/Decoder for X-band Nano Satellite High-Speed Downlink System

Nano satellite technologies have been recognized as potential candidates for new satellite applications. We have developed a X-band downlink system for nano satellite employing Consultative Committee for Space Data Systems (CCSDS) 131.2-B-1 signaling formats with a modulation symbol rate of 100 Msps. Since nano satellites with a mass of less than 50 kg have more constraints than typical large s...

Iterative Equalization and Decoding for theGSM {

In iterative equalization and decoding (\turbo-detection") the \turbo{principle" is used for detection of coded data transmitted over a frequency selective channel. Due to the burst and interleaver structure the turbo-detection scheme cannot be adopted to the GSM without modiications. We present some possibilities to adopt turbo detection to TDMA systems with inter-block-interleaving like GSM a...

An Efficient Channel Equalization on the Transmission of Turbo Coded Signals

This paper addresses the problem of channel equalization and tracking in turbo coded signals over frequency selective fading and delay spread channels. An innovative turbo equalization structure is presented jointly with the iterative decoding process, which is based on performing channel equalization via double decision feedback equalizer (DDFE) designed by using noncomplex least mean square a...
