Transmission

An LPC vocoder (Linear-Predictive Coder), is a lossy compression technique that is highly optimized for low-bitrate speech transmission.The problem here that we solve is to take a speech waveform with an 8kHz sampling rate, code it to a much lower bit-rate so that it can be transmitted over a...

In this project, we seek to minimize the gap-to-capacity (given by Shannond-deOaos theoretical limit) of a rate 1/3 code (also can be modified for 1/N). This is done via a convolutional encoder/decoder for varying memory elements as well for both soft and hard decoding scheme. We show that the... Platforms: Matlab

Httping is like 'ping' but for http-requests. Give it an url, and it'll show you how long it takes to connect, send a request and retrieve the reply (only the headers). Be aware that the transmission across the network also takes time! So it measures the latency of the webserver + network. Platforms: Mac
