Source: Constant Wave press release
Constant Wave, a developer of innovative RF signal processing software, has published source code for LTE waveform generation on its web site at http://www.ConstantWave.com/lte_source_code.aspx . Releasing C++ source code to the public domain can simplify the implementation of this challenging standard. In addition, it allows users of Constant Wave’s Spectro LTE Gen software to examine the core algorithms that construct LTE signals. This is a key issue for standards which are still evolving, such as LTE.
