Drawkcab Gnimmargorp: Test-Driven Development With FUTS

One of the practices of Extreme Programming is Test-Driven Development TDD, also known as Test-First Design. This style of development emphasizes an approach that is backwards to many programmers: writing tests before working code. Interestingly, this approach has found application in both agile methodologies and validation-intensive programming environments. TDD involves...

Compress-and-Forward Cooperative Relaying in MIMO-OFDM Systems

This paper investigates the capacity of Compress-and-Forward (C&F) cooperative relaying scheme when the C&F relay operates in Time Division Duplex TDD. In the evaluation it considers MIMO-OFDM transmission. An achievable rate was previously derived in assuming scalar channel. This paper extends this Wyner-Ziv bound to MIMO-OFDM, by applying results from...

Further Vision on TD-SCDMA Evolution

As the data rate of the mobile service increases fast, 2Mbps is not enough any more for Time Division-Synchronous Code Division Multiple Access (TD-SCDMA). While the new B3G system to provide high data rate service is still in research, TD-SCDMA must be enhanced and evolved to provide higher data rate...

Channel Capacity of TDD-OFDM-MIMO for Multiple Access Points in a Wireless Single-Frequency-Network

The Multiple-Input-Multiple-Output MIMO technique is the most attractive candidate to improve the spectrum efficiency in the next generation wire-less communication systems. However, the efficiency of MIMO techniques reduces in the Line Of Sight LOS environments. This paper proposes a new MIMO data transmission scheme, which combines Single-Frequency-Network SFN with TDD-OFDM-MIMO...
