چکیده

We explore the possibility of using an emerging tool in statistical signal processing, sequential importance sampling (SIS), for joint estimation and decoding of space-time trellis codes (STTC). First, we provide background on SIS, and then we discuss its application to space-time trellis code (STTC) systems. It is shown through simulations that SIS is suitable for joint estimation and decoding of STTC with time-varying flat-fading channels when phase ambiguity is avoided. We used a design criterion for STTCs and temporally correlated channels that combats phase ambiguity without pilot signaling. We have shown by simulations that the design is valid.

Joint Decoding and Channel Estimation for Space-Time Codes

We consider the problem of joint decoding and channel estimation for space-time trellis codes transmitted over f lat slowly varying Rayleigh fading channels. We assume that the receiver has no a-priori knowledge of the channel parameters. The amount of training data required is reduced by using a decision feedback approach to iteratively improve channel estimates.

Joint Decoding of Concatenated VLEC and STTC System

We consider the decoding of wireless communication systems with both source coding in the application layer and channel coding in the physical layer for high-performance transmission over fading channels. Variable length error correcting codes (VLECs) and space time trellis codes (STTCs) are used to provide bandwidth efficient data compression as well as coding and diversity gains. At the recei...

Performance analysis and iterative decoding of I-Q trellis space-time codes

I-Q trellis codes are known to increase the time diversity of coded systems.When I-Q codes are used with multiple transmit antennas, the decoding and performance evaluation requires the construction of the high-complexity super-trellis of the component codes. In the paper, the bit error probability and the design criteria of I-Q space-time (ST) codes are derived using the transfer functions of ...

Multi-layered Space Frequency Time Codes

This dissertation focuses on three major advances on multiple-input multiple-output (MIMO) systems. The first studies and compares decoding algorithms for multi-layered space time coded (MLSTC) systems. These are single user systems that combine spatial multiplexing and transmit diversity. Each layer consists of a space time code. The detection algorithms are based on multi-user detection theor...

International Journal of Computer Science and Intelligent Computing (IJCSIC)

We introduce a new family of space–time trellis codes that space–time block codes as building blocks in our new trellis codes. These codes combine set partitioning and a super set of space–time block codes in a systematic way to provide full diversity and improved coding gain.. It is also possible to maintain a tradeoff between coding gain and rate.. Simulation result (i.e. frame error rate) sh...
