Partial Feedback Based Orthogonal Space-Time Block Coding With Flexible Feedback Bits
نویسندگان
چکیده
The conventional orthogonal space-time block code (OSTBC) with limited feedback has fixed feedback bits for the specific transmit antennas. A new partial feedback based OSTBC which provides flexible feedback bits is proposed in this paper. The proposed scheme inherits the properties of having a simple decoder and the full diversity of OSTBC, moreover, preserves full data rate. Simulation results show that for transmit antennas, the proposed scheme has the similar performance with the conventional one by using 1 p

Adaptive Channel Matched Extended Alamouti Space-time Code Exploiting Partial Feedback
Biljana Badic et al. 443 Since the publication of Alamouti’s famous space-time block code, various quasi-orthogonal space-time block codes (QSTBC) for multi-input multi-output (MIMO) fading channels for more than two transmit antennas have been proposed. It has been shown that these codes cannot achieve full diversity at full rate. In this paper, we present a simple feedback scheme for rich sca...
متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
متن کاملPre-coded Orthogonal Space-Time Block Codes over MIMO Channel and its Analysis for Antenna Selection Technique
A pre-coder is designed for orthogonal space-time block codes (OSTBCs) in multiple-input multiple-output (MIMO) channels. Unlike previous works, our pre-coder is the first to be designed to minimize the exact symbol error rate. In this paper, we show that OSTBCs can achieve full diversity and nearly strict orthogonality with a small amount of feedback bits returned from the receiver back to the...
متن کاملPartial Feedback Based Orthogonal Block Coding
Over the last couple of years a number of spacetime block codes have been proposed for use in multiple transmit antennas systems. In this article we propose a method to extend any space-time code constructed for m transmit antennas to m p transmit antennas through GroupCoherent Codes (GCC). GCC make use of very limited feedback from the receiver (as low as one bit). In particular the scheme can...
متن کاملClosed Loop Quasi-Orthogonal STBC for Multiple Transmitters and Multiple Receivers
This paper presents how to design Quasi-Orthogonal Space Time Block Coding for multiple transmitting antennas and one receiver with feedback. Multipath wireless environment creates difficulty because of diversity at multiple receivers and multiple transmitters. Diversity is reduced by using Quasi-Orthogonal STBC. For simplicity we considered four transmitters and one receiver. The diversity is ...
