Abstract
A radio data communication system includes a plurality of radio units, each radio unit having a transceiver and an antenna, and a gateway unit connected to each of the plurality of radio units via a first data bus. Each transceiver in the plurality of radio units is configured to receive a data signal from a respective antenna, compress the received data signal using a data compression algorithm, and transmit the compressed data signal to the gateway unit via the first data bus. The data compression algorithm includes a bit shifting operation performed by a multiply-accumulate operation.

A radio data communication system comprising:
- a plurality of radio units, each radio unit having a transceiver and an antenna;
- and
- a gateway unit connected to each of the plurality of radio units via a first data bus,
- wherein each transceiver in the plurality of radio units is configured to:
- receive a data signal from a respective antenna;
