- Conversion of MP3 to AAC in the Compressed Domain
- This paper proposes an efficient algorithm for conversion of an MP3 stream into Advanced Audio Coding AAC. Generally, this kind of conversion, transcoding, requires full decoding and reencoding. However, the re-encoding based transcoding process may result in degradation of quality and take longer than encoding from a PCM signal. This...

- Performance Degradation of OFDM and MC-CDMA to Carrier Phase Jitter
- This paper analyses the effect of carrier phase jitter on the performance of OFDM and MC-CDMA waveforms. Assuming a multicarrier downlink through an AWGN channel, this paper investigates the impact of jitter phase models on the SNR degradation. This paper proposes to consider a small random process, a gaussian process...

- The Changing Face of Network Management
- Managing the network is serious business. It is absolutely essential that it is up and running since the critical business services depend on it - and so does the revenue stream. At the same time, the network continues to grow in size and complexity, with the addition of more devices...

- Optimizing TCP Retransmission Timeout
- Delay spikes on Internet paths can cause spurious TCP timeouts leading to significant throughput degradation. However, if TCP is too slow to detect that a retransmission is necessary, it can stay idle for a long time instead of transmitting. The goal is to find a Retransmission Timeout RTO value that...

- Impact of Layer 2 Behavior on TCP Performance in WLAN
- Ubiquitous networks enabling access by Mobile Nodes MNs at any time and at any location will consist of several different Wireless LANs WLANs, so it is likely that an MN will traverse several WLANs during communication. In such a case, avoiding performance degradation during the handoff becomes a critical issue....

- A Symbol Estimation Scheme for Alamouti Coded OFDM Systems
- In Alamouti coded OFDM 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...

- TCP-Planet: A Reliable Transport Protocol for InterPlaNetary Internet
- The space exploration missions are crucial for acquisition of information about the space and the universe. The entire success of a mission is directly related to the satisfaction of its communications needs. For this goal, the challenges posed by the InterPlaNetary Internet need to be addressed. Current TCP protocols have...

- Influence of Power Control and Link-Level Retransmissions on Wireless TCP
- A fundamental assumption of the tcp protocol is that packet losses indicate congestion on the network. This is a problem when using tcp over wireless links, because a noisy radio transmission may erroneously indicate congestion and thereby reduce the tcp sending rate. Two partial solutions, that improve the quality of...

- The Effectiveness of Signal Clipping for PAPR and Total Degradation Reduction in OFDM Systems
- Signal clipping has been suggested as an effective Peak-to-Average Power Ratio PAPR reduction scheme for orthogonal frequency-division multiplexing OFDM. This paper analyzes clipped M-ary differentially encoded phase-shift keying (M-DPSK) OFDM. The impact of Input Power Backoff IBO of a nonlinear Power Amplifier PA is evaluated. An effective PAPR reduction scheme...

- Enhancing Cable Modem TCP Performance
- This white paper discusses the inherent bi-directional behavior of TCP and its performance when used in conjunction with the DOCSIS MAC protocol. It provides typical examples of degradation in TCP throughput and describes how the addition of application awareness and acknowledgment filtering software can be used to improve TCP throughput.
