3GPP Long Term Evolution Physical Layer

3GPP Long Term Evolution (LTE) physical layer is a complex computational block of the next generation mobile technology. It supports high data rates thereby facilitating various multimedia services on a mobile device for the benefit of the end-user.

TCS has developed LTE Layer 1 reusable components, which can be used for the development and validation of eNB and UE respectively.
