Standards-Compatible Method for Near-Best Signal Throughput in Mobile Wireless Communications


Marketing Title: Standards-Compatible and Near-Best Transmission Method for Enhancing Throughput in Mobile Communications


Non-Confidential Description:

This novel signal transmission method significantly increases throughput in modern wireless systems, e.g., LTE/LTE-A., and is shown to be near-optimal. The method is standards-compliant and compatible with existing wireless network hardware, therefore offering cost-effective implementation and fast integration with existing standards. This technology embeds data information together with the pilots that are required by any wireless systems while maintaining the effectiveness of the pilots. It has been shown that the invention will increase data rate, on average by 20-30% and in some specific conditions by up to 80%. 


In mobile systems, especially cellular networks, a base station serves multiple users simultaneously. The most popular technique is to send data to different users in different time or frequency, so that the users will not experience interference. However, this technique does not maximize the network throughput, and sometimes operates far below the theoretical capacity of the network, especially when the network has various types of users.


Potential Applications:

·         Cellular networks

·         Wireless LAN and ad-hoc networks

·         High-mobility receivers

·         Multi-antenna communication

Potential Benefits:


·         Higher throughput – compared with conventional methods in networks with different mobility, at all signal-to-noise ratios.

·         Standards Compliant – all users need only process the mixed signal at nominal cost.

·         Retro-compatible – compatible with previous standards.
