Operation for backward-compatible transmission

摘要

The present invention relates to a transmitter in a transmission system operable to optimize estimates of a quantity at a receiver for improved operation. The transmission system includes a transmitting unit connected to a number of antennas (Txm), and to control unit. The control unit controls the transmitting unit to initially transmit an initial training/quantity estimation sequence during an initial training/quantity estimation phase and subsequently transmit a sequence of data symbols such that the information rate of the data symbols is progressively increased.

1. A transmission system including a transmitter operable to optimize estimates of a quantity at a receiver for improved operation, comprising:
a transmitting means operably coupled to a plurality of antennas (Txm); and a control means operably coupled to the transmitting means, wherein the control means is configured to control the transmitting means to transmit an initial training/quantity estimation sequence of a data packet during an initial training/quantity estimation phase and subsequently transmit a sequence of data symbols of the data packet such that the information rate of the data symbols is progressively increased, during the transmission of the data symbols; wherein a first part of the sequence of data symbols is transmitted using a first data rate and a second part of the sequence of data symbols is transmitted using a second data rate with the second data rate being higher than the first data rate.
