- Considering dropping cable for satellite
- I'm considering dropping cable television service for a satellite service because of Time-Warner's prices. I don't care about premium movie services, pay-per-view events, sports packages, on-demand services, or anything outside one of the 150- or 200-channel packages. I'd like one HD / DVR receiver and a second "plain"...

- Efficient Detection of Zero-Padded OFDM Signals With Large Blocks
- This paper presents a frequency-domain receiver for ZP-OFDM schemes (Zero-Padded Orthogonal Frequency Division Multiplexing) where the duration of the channel impulse response is a significant fraction of the duration of the OFDM block. The proposed receiver has a relatively low complexity, allowing an FFT-based Fast Fourier Transform implementation. The proposed...

- Audio connect from PC to analog receiver
- The PC has a 2 channel, female, audio out line for minipin and a similar looking one (Toslink?) for SPDIF. Non-digital receiver has white and red RCA females for audio in. Using the analog out results in a persistent speaker buzzing that sounds very similar to the audible running sound...

- Low Complexity OFDM Detector for Underwater Acoustic Channels
- An adaptive algorithm is proposed for OFDM signal detection on Doppler-distorted, time-varying multipath channels. The focus of the approach is on low complexity post-FFT signal processing. The receiver performs MMSE combining of signals received across an array, using adaptive channel estimation. Nonuniform Doppler compensation across subbands is performed using a...

- A Space-Time Receiver for MIMO-OFDM Ad Hoc Networks
- This paper proposes a receiver architecture that can demodulate multiple data streams with different frequency offsets and propagation delays in Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) ad hoc networks. The receiver performs joint synchronization and interference cancellation to separate these interfering data streams and achieve synchronization for...

- Choose a network troubleshooting methodology
- Many network administrators don't use an official methodology when it comes to troubleshooting network problems, but there's something to be said for taking a more formal approach. David Davis examines three network troubleshooting methodologies and discusses the advantages of each approach. A decent portion of every network administrator's job...
