Abstract

A gear shifting technique has been developed in which modulation and equalization are shifted to achieve optional performance. In one form, two or more equalizers, each associated with a demodulator and message decoder, determine if the modulation being used can be increased in complexity in order to increase the channel throughput or determine if the modulation method should be reduced in complexity in order to improve the receiver error performance. The quality metrics can based on which equalizer-demodulator-decoder is set to first detect a valid message. Other factors can be considered with this technique such as a packet-error ratio and a signal-to-noise ratio. In a financial trading system, message erasures can be favored over errored messages by limiting the number of bit or symbol corrections permitted per message to less than the maximum possible for the selected decoding schemes.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 767,179, filed November 14, 2018, which is hereby incorporated by reference. Background technique [0003] Typical over-the-air (OTA) radio transmissions can have significant delays when traveling over long distances, such as across oceans. Furthermore, these transmission channels can be quite noisy, which in turn increases the need for error correction. The high frequency (HF) radio communication channels of most long-range communication systems are limited at any one time by the available allocated radio bandwidth and channel capacity. When high-frequency radio channels are used in financial high-frequency trading applications, this limited bandwidth can cause delays in receiving financial instructions, which in turn can adversely affect finance. [0004] Therefore, improvements are needed in this area. Contents of the invention [0005] ...
