A Decision Directed Receiver for Alamouti Coded Ofdm Systems
نویسندگان
چکیده
When the Alamouti code is applied (as a space-time block code) to an OFDM system with transmit diversity, the simple Alamouti decoding requires that each subchannel is flatfading and constant over two symbol periods(Alamouti codeword period). The second requirement makes the Alamouti decoding scheme not suitable for time varying channels. In this paper, we propose a new decision directed receiver to better accommodate time varying channels.

A Symbol Estimation Scheme For Alamouti Coded OFDM Systems
Abslmct-In Alamouti coded O F D M systems, the simple decoding at the receiver relies on the assumption that the subchannels are flat fading, decoupled, and quasi-static so that each subchannel does not change over an Alamouti codeword period (two consecutive OFDM symbol periods). When the channel is fast fading, however, these assumptions are not met, resulting in severe performance degradatio...
متن کاملSelective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

Additive mapping scheme represents alternative signals of selected mapping (SLM) by linear combination of signals in time domain for peak to average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) system.

In this paper we present an analytical approach to evaluate the M-QAM symbol error rate (SER) of Alamouti space time coded OFDM direct conversion receivers subject to carrier frequency offset (CFO), channel estimation errors, outdated channel state information, limited ADC resolution and flat receiver I/Q imbalance in Rayleigh time and frequency selective fading channels. The SER is numerically...
متن کاملCapacity and Performance Analysis of Space-Time Block Coded MIMO-OFDM Systems over Rician Fading Channel
This paper presents an analysis on the capacity and performance of MIMO-OFDM systems. The work is focused on the capacity of MIMO-OFDM systems over rician fading channel, in the case of the channel being known at the receiver only, which is more practical case of the channel. Simple expression for capacity is derived for the case of correlated rician fading. The performance of some MIMO-OFDM im...
